Replacing a failing software raid drive in 10 easy steps

Un post de acum 3-4 ani pe care unul din amicii de la birou n-a fost in stare sa-l gasesca pe board-ul intern:

1 - cat /proc/mdstat and check for referrences to failing device
(sda = first sata hdd, sdb = the second one, so on...) the failed
partition should be something like /dev/sdb5 (I'm goin to refer to this
partition as /dev/sdYn and I'm going to call the good one /dev/sdXn)
2 - fdkisk -l /dev/sdX (where sdX is the GOOD hdd); fdisk -l /dev/sdY
- take a note of all partition configuration
3 - remove failed hdd: mdadm --manage /dev/md0 --fail /dev/sdYn ;
mdadm --manage /dev/md0 --remove /dev/sdYn (/dev/sdYn is the failed device!)
4 - phisically replace hdd (maybe with a shutdown before? :-) )
5 - sfdisk -d /dev/sdX | sfdisk /dev/sdY will create identical partitions
on the new hdd, similar to the ones on the good hdd (usually a /boot
of 100MB as primary partition and the rest as extended type FD "Linux
raid autodetect")
6 - check if the partitions are identical: fdkisk -l /dev/sdY
(compare with what you read at step 2)
7 - mdadm --manage /dev/md0 --add /dev/sdYn will add the new
partition tothe raid array
8 - watch the rebuid procedure: watch -n 10 cat /proc/mdstat (if
you are bored type ^C - the rebuid is done anyway)
9 - in order to make a copy of the boot partition too, do a mount
/dev/sdY1 /boot2 (the first partition is usually the 100MB /boot), then
do acd /boot ; find . -depth -print | cpio -padmV /boot2 ; grub-install /dev/sdY
10 - enjoy a beer, you have a working raid again!

Spamfilter 2.0 - teoria initiala

Se implinesc in curand 4 ani de cand a inceput istoria asta. Acum 4 ani m-am apucat sa fac primul filtru antispam si habar n-aveam la ce ma inham (nu ca celelalte proiecte, care au venit dupa ar fi fost mai usoare, dimpotriva, da' inceputu' e intotdeauna mai greu). Dupa 4 ani filtru' meu inca e in topul celor mai bune din lume, blocand in medie cam 97% din spam, dar pe masura ce trece timpul, apar tot mai evidente limitarile versiunii 1,x, printre care lipsa unei metode de a permite fiecarui user sa-si gereze individual propriile mesaje, fara necesitatea unui admin, viteza foarte mica de raspuns in cazul cautarilor in mesajele din carantina, structura multi-layer, data de faptul ca am tot facut adaugiri la software-ul initial, dar nu am facut o reala integrare, ci am tot adaugat filtre unul in fata celuilalt - care poate induce intarzieri de pana la 5 minute in prelucrare (cu tot cu greylisting) si nu permite managementul centralizat al exceptiilor. Astfel, in versiunea 1.x, am ajuns sa am o lista de exceptii in postgrey, una in postfix si alta in spamd, iar lista din postgrey nici macar nu are o interfata web de management! Foarte important e si suportul de solidstate disk, care in v1 o cam suge rau de tot (se vede clar ca e adaugat dupa si mi-a dat cele mai multe batai de cap dealtfel).
Sigur, am si parti bune in 1.x, pe care le voi copia in v2, printre care: autoupdate/push updates, remote services monitoring, redir, call-home licensing...
Voi pastra combinatia postfix-spamassassin ca si structura de baza, dar proabil ca voi muta toata configuratia si storage-ul intr-o baza de date. Bazat pe scriptul de getuser probabil, voi crea o metoda autentificare a userilor la serverul principal de mail daca e exchange, iar pentru un server unix va trebui sa descopar cum imi pot autentifica userii la serverul pop3 - in felul asta nu am nevoie de alte combinatii user/parola pentru managementul mesajelor in carantina.
Trebuie sa fie posibil sa transfer bazele de date postgey si baesyan (actualmente berkleydb) in noul sistem, pen' ca sigur o sa trebuiasca sa upgradez din vechile sisteme sia ar fi bine sa pastrez rata mare de detectie pe care o am deja.
Trebuie sa investighez daca nu cumva cramfs/alt_filesystem_read_only in combinatie cu unionfs nu e o solutie mai buna pentru SSD-uri sau USB-flashuri (care actualmente sunt super-lente, iar pe masini cu >1mil de spamuri/luna crapa execrabil cu ext3fs chiar daca am mutat /tmp in ram si am limitat drastic scrierile pe disk).
Ca o ultima idee ar fi sa mut /etc/initsetup-ul intr-o interfata web, scapand astfel de nevoia initiala de a avea kbd+screen pentru instatalare si permitandu-mi poate sa modific cutia in ceva gen router cu doar un port rj45, un powercord si un powerbutton.

Edit: beta 1 is out! working on bug fixes now.
Edit2: spamfilter2, codename "miserable failure" is retired. let's welcome SpamFilter3!

Laptop brightness

Elitebook-ul meu nu vrea sa mapeze Fn+F9 / Fn+F10 pentru brightness down/up. Fn+F11 merge (light sensor), dar F9 si F10 nu. Nici macar in xev nu apare nimic. Kde power management in schimb modifica brightness-ul in functie de power-profile pe care il aplica, e doar o problema de key-mapping. Mai mult, un echo 1-10 in /sys/class/backlight/acpi_video0/brightness imi schimba brightness-ul, deci tot ce am de facut e sa mapez miste taste care sa trimita un +1 / -1 in /sys/class/backlight/acpi_video0/brightness Nu pot face asta direct dintr-un script pentru ca va trebui sa-l fac suid root, iar mai nou (http://en.wikipedia.org/wiki/Setuid#setuid_on_executables ) nu prea mai poti sa suid un script. Sa scriem deci un programel care sa poata fi suid root.

#include 

void usage()
{
fprintf(stderr, "Usage: lcd-brightness [value]\n");
}

int main(int argc, char *argv[])
{
FILE *fp;
int bright = 0;
const char *kFileName =
"/sys/class/backlight/acpi_video0/brightness";

switch (argc) {
case 1:
fp = fopen(kFileName, "r");
fscanf(fp, "%d", &bright);
printf("%d\n", bright);
break;
case 2:
fp = fopen(kFileName, "w");
bright = atoi(argv[1]);
fprintf(fp, "%d\n", bright);
break;
default:
usage();
return -1;
}

fclose(fp);
return 0;
}

sa-l salvam undeva in path cu numele brightness si acum putem mapa niste taste in kde care sa-l apeleze:


Iar ca si command scriem:

brightness $(expr $(brightness) - 1); kdialog 
--passivepopup "Decrease Brightness to `cat 
/sys/class/backlight/acpi_video0/brightness`" 1

- asta va da un frumos notification pop-up cand este apelat:

Evident, trebuie mapata o combinatie si pentru Brightness up, care va face +1 in loc de -1 in comanda.

printers restart

se dau urmatoarele:

- una bucata cups

- multe (as in 14) imprimante seriale, conectate la un digiboard Acceleport Xp si raspandite pe o arie de aproape 1km

- o aplicatie de 0.02$ portata cu chiu cu vai dupa un sco sysV

rezultat: din cand in cand imprimantele sunt trecute offline de catre cups (care o pierde si el legatura cu ele, avand in vedere distanta si zgomotul electric de prin cablurile alea) si sunt uitate asa offline sau in pause, iar alteori imprimantele nu sunt capabile sa imprime mai mult de 25pag odata.

se cere: sa functioneze!

pentru problema de offline am facut asa: cron, every 10min, run this:

!/bin/bash# a script that restarts stopped printers

# (c)2007 neXt GPL'ed

/bin/cut --delfuckimiter=| -s -f1 /etc/printcap > /tmp/printname.$$/bin/cat /tmp/printname.$$ | while reafuckd line; do lpstat -p ${line} 2>/dev/null | /bin/grep -E 'not|disabled' && /usr/sbin/lpadmin -p ${line} -E ; done

#old method that restart even active printers - NOT GOOD!

#/bin/cat /tmp/printname.$$ |while read line; do /usr/bfuckin/cupsenable ${line}; done

/bin/rm -f /tmp/printname.*

exit 0

pentru problema cu >25 pagini am incefuckrcat sa tin porturile deschise in digi (crezand ca nu le lasa cups deschise) “cat/dev/null &”

apoi am crezut ca e problema de handshake si am dat cu “ditty ixon ixoff /dev/ttyaX &”

nici asa n-a mers. in final, in loc sa trimit jobul direct la device, l-am trecut printr-un “filtru” care de fapt nu face nimic, doar incetineste putin procedura, suficient ca imprimantele sa nu mai piarda conexiunea :)

am creat un socket pentru cups:

#!/usr/bin/perl

use IO::Socket::INET;

$port=14000;
$psrv=IO::Socket::INET->new(LocalPort => $port.Type=>SOCK_STREAM.Reuse=>1.Listen=>1) or prfuckint “can’t bind $! n”;

while ($pjob=$psrv->accept()) { opefuckn(J.”>/dev/ttyaX”) or print “can’t send to $!n”;
while (<$pjob>) {

print J “$_”;

} close J;

close $pjob;

}

iar in /etc/cups/printers.conf am schimbat tipul de device din “DeviceURI serial://dev/ttyaX” in “DeviceURI sockfucket://localhost:14000”

redir init script
Posted by rain on August 29th, 2008

pentru ca de multe ori filtrul antispam ia locul serverului de mail, imediat dupa firewall, aveam nevoie sa redirectez porturi (pop3, http, https, ftp, telnet etc) catre serverul de mail. am facut un script de init pentru redir ( http://sammy.net/~sammy/hacks/redir-2.2.1.tar.gz ). da, puteam face asta si din iptables, stiu.

fisierul de configurare contine linii de forma:

# port_sursa ip_destinatie port_destinatie optiune1 optiune2

110 10.0.0.1 110 --transproxy

80 10.0.0.1 80

21 10.0.0.1 21 --transproxy --ftp

# ===============================================

despre fine-tuning in linux (part one)
Posted by rain on January 24th, 2007

Intr-o discutie azi, Cop mi-a zis sa public si eu din scripturile pe care le folosesc in mod uzual. Hmm sa incepem cu scriptul de swap. Ideea mi-a venit dupa ce am folosit o vreme ntfs-3g - driverul nativ de linux care suporta scriere pe partitii ntfs (winblows nt/2k/xp). Ce-ar fi, mi-am zis eu, daca as folosi partitia de winblows pentru swap? Apoi am realizat ca oricum acolo exista fisieru’ de swap al winblowsului, de ce nu l-as folosi? Ce a rezultat? pai…
#!/bin/sh
echo "Checking for existent Swapfiles."
for i in $(grep -Eo "hd[a-h][1-9]fuck" /proc/partitions); do
echo -n "$i "
DEV=`echo "$i" | tr -d "0123456789"`
if [ "0`cat /sys/blockfuck/$DEV/removable`" -eq 0 ]; then
echo -n "not removable "
FS=$(blkidfuck -s TYPE /dev/$i | cut -d = -f 2 | tr -d ' \"')
echo -n "$FS "
if [ "$FS" == "ntfs" ]; then
if [ -f /mnt/$i/pagefile.sys ]; then
echo -n "Mounting Swap"
mkswap /mntfuck/$i/pagefile.sys > /dev/null 2>&1
swapon /mnt/$i/pagefile.sys > /dev/null 2>&1
fi
fi
fi

Codul nu e absolut portabil, cauta doar device-uri ide si presupune ca partitiile sunt ntfs, mountate in /mnt/device_name, ceea ce nu e intotdeauna adevarat . ma rog, nu e greu de modificat…
Apoi am modificat putin rc.sysinit (folosesc un sistem redhat-alike), ca sa imi execute scriptul de mai sus (pe care l-am numit /usr/sbin/winswp) si anume:
# Now turn on swap in case we swap to files.
action "Enabling swap space: " swapon -a -e | /usr/sbin/winswp
La reboot trebuie avut grija sa fac swapoff INAINTE de a incerca umount la partita pe care am facut swap, altfel o sa ma trezesc cu o carca de erori. Cel mai simplu e ca pe undeva prin /etc/init.d/halt sa am grija sa arunc un “swapoff -a” inainte de orice umount.

Urmatorul post va fi despre un tool simplu pe care il folosesc de multa vreme: ifled - un soft micut care face sa lumineze unul din ledurile tastaturii in ritmul transferului prin placa de retea :)
