Dotaz: OpenVZ - debian guest - quotas

[rrob]

Sedim nad tim pul dne a nic jsem nevygooglil. Mam pronajaty virtualni server, cele to bezi na openvz a jako guesta jsem si nainstalil debian lenny. Zkousel jsem postupovat podle vsemoznych navodu: http://www.debianadmin.com/implement-and-manage-disk-quotas-in-linux.html http://www.howtoforge.com/how-to-set-up-journaled-quota-on-debian-lenny

Ve fstab mam
#cat /etc/fstab
proc  /proc       proc    defaults    0    0
none  /dev/pts    devpts  rw          0    0

root / tam vubec nadefinovany neni ale kdyz dam vypis pripojeni
# mount
/dev/simfs on / type reiserfs (rw,usrquota,grpquota)
tak se tam jakoby s kvotami pocita.

Otazka cislo jedna - mam do fstab zadavat parametry v tutorialech zminovane? a jak prizpusobit radek v tomto pripade kdy se jedna o virtualni filesystem.

Nasledujici jiz zrejme plyne z nenastaveni ve fstab.

#touch /aquota.user /aquota.group
#chmod 600 /aquota.*
#mount -o remount /
mount: permission denied
(vse delam samozrejme jako root)

protoze se mi nepodarilo remountout fs tak jsem cely os rebootnul - coz povazuji za stejne

pote zadavam

#quotacheck -avugm
a dozvidam se ze:
quotacheck: Your kernel probably supports journaled quota but you are not using it. Consider switching to journaled quota to avoid running quotacheck after an unclean shutdown.
quotacheck: Quota for users is enabled on mountpoint / so quotacheck might damage the file.
Please turn quotas off or use -f to force checking.

tak tedy pridavam f

# quotacheck -avugmf

abych se dozvedel dalsi chyby:

quotacheck: Your kernel probably supports journaled quota but you are not using it. Consider switching to journaled quota to avoid running quotacheck after an unclean shutdown.
quotacheck: WARNING -  Quotafile //aquota.user was probably truncated. Cannot save quota settings...
quotacheck: WARNING -  Quotafile //aquota.group was probably truncated. Cannot save quota settings...
quotacheck: Scanning /dev/simfs [/] done
quotacheck: Checked 2095 directories and 27568 files
quotacheck: Cannot find checked quota file for users on /dev/simfs!
quotacheck: Cannot find checked quota file for groups on /dev/simfs!

vezmu to od spodu - nemuze najit quota file - pokud to jsou ty prave vygenerovane v / tak ty tam jsou:

# ls -l *quota*
-rw------- 1 root root    0 30. čen 15.42 aquota.group
-rw------- 1 root root 9216 30. čen 15.45 aquota.group.new
-rw------- 1 root root    0 30. čen 15.42 aquota.user
-rw------- 1 root root 7168 30. čen 15.45 aquota.user.new

ale jsou prazdne.

Proc nemuze ulozit "Cannot save quota settings..." a co mu vadi tady "WARNING - Quotafile //aquota.group was probably truncated." vskutku nevim.

Nasledujici prikaz uz je asi po predeslych errorech zbytecny ale pro uplnost:

# quotaon -avug
quotaon: Cannot find quota file on / [/dev/simfs] to turn quotas on/off.
quotaon: Cannot find quota file on / [/dev/simfs] to turn quotas on/off.

Je-li to dusledek nezadani informaci do fstab, pak se omlouvam za zbytecne otazky ale pls poradte co si procist abych zjistil jak fstab v opnevzovanem debianu nastavit.

Diky moc.

Tak to je jeden z  problemu, ktere te s OpenVZ ceka.

Modri jiz vedi a jedou ve virtualu na xenu :)

Ja jsem totalne modry a sve servery mam pocitrixovane. Problem je v tom ze nejsou v garantovanem housingu na pateri. Proto jsem si na zkousku vzal komercni virtualni hosting a ten prave jede na openvz.

Po prejmenovani aquota.group.new na aquota.group pokracoval pribeh takto:

# quotaon -avug
quotaon: using //aquota.group on /dev/simfs [/]: Device or resource busy
quotaon: using //aquota.user on /dev/simfs [/]: Device or resource busy

Pro ty, co to hledaji, tak poskytovatel vps by mel udelat toto - presnejsi vyznam si jiz prectete v dokumentaci.

# vzyum VEID install quota # vzctl set VEID --quotatime 0 --quotaugidlimit 500 --save # vzctl restart VEID Change quotatime and quotaugidlimit as required.

Pro ty, co to hledaji. Budte modří a hotovo .) Proste jsem poskytovatel pozadal jestli mi openvz hosting nevymeni za xen hosting ktery se mu objevil v nabidce a hotovo. Kazdopadne ale dekuji za reseni.
