Quota Problem: quotaon error

Bruno Rebelo Lobato — Thu, 09 Jun 2005 12:45:43 GMT

I follow these steps to enable quota in my home users partition:

#cpset /dev/null /export/home/quotas 600 root bin

Then i enable quota for user blobato.
#edquota blobato

I Modify the line /etc/fstab like this
/dev/vgRAID1/lvolhome /export/home vxfs rw,suid,largefiles,delaylog,datainlog,quota 0 2

then i reboot my L2000 server.
But when the server come up, i saw my /etc/mnttab that the quota option not be active :
/dev/vgRAID1/lvolhome /export/home vxfs log,nodatainlog 0 0 1118322353

Then i try run :
#quotaon -v /export/home

but i received the following message :

quotactl: /dev/vgRAID1/lvolhome: I/O error

The most strange is, i have other partitions (vxfs) with quota running FINE, like you see in this output :
root : quotaon -av
/training: quotas turned on
/temp_teste: quotas turned on
quotactl: /dev/vgRAID1/lvolhome: I/O error

Can anybody help-me, please. I need to activate the quota on home users.

Thank's.

Are there any problems with that lvol??
Check dmesg/syslog. mount -p | grep "lvol" Is lvol mounted with quota option??

Also make sure you correctly updated fstab. Also when you rebooted system, did you see anything wrong, any error messages for this lvol??

Hi,
In your home directory you should find a file called quotas with perms rw only to root, is it there?
Then try:
Unmount /export/home
mount -o quota /dev/vgRAID1/lvolhome /export/home

Good luck
Victor

>> Are there any problems with that lvol??

No, the lvol is ok and working.

>> Check dmesg/syslog. mount -p | grep "lvol" Is lvol mounted with quota option??

The output off this command is the /etc/mnttab file, how i said in my post in the mnttab the quota option don't is showed but i set up the quota option in the /etc/fstab before boot my server.

>>Also make sure you correctly updated fstab.

Yes, please see :
/dev/vgRAID1/lvolhome /export/home vxfs rw,suid,largefiles,delaylog,datainlog,quota 0 2

Also when you rebooted system, did you see anything wrong, any error messages for this lvol??

No, everything is fine. with all the partions, but only in this i can't up the quota service :-(

>> In your home directory you should find a file called quotas with perms rw only to root, is it there?

Yes, see :
-rw------- 1 root bin 0 Jun 9 15:25 quotas

>> Then try:
Unmount /export/home
mount -o quota /dev/vgRAID1/lvolhome /export/home

I can't umount my home partition at this moment, but when i try this :

mount -o remount,quota /dev/vgRAID1/lvolhome /export/home/
vxfs mount: cannot enable quotas

The point is, i have others partions in the same server, and in this other partitions the quota option works :-(.

Any other sugestions ?

Thank's.

I/O error indicates problem with physical media. Find out what physical volumes are on this logical volume, then check if have any stale extents on each disk. You can also test disks by running dd on each disk device file and sending output to /dev/null.

# dd if=/dev/rdsk/cxtxdx of=/dev/null bs=64k

All the extents are "current", and the dd command work's fine, whithout problems.

Any other sugestion ?

Bruno,

You are sure you are using quotas on a vxfs filesystem ?

# fstyp -v /dev/vgRAID1/rlvolhome

Did you try to use the quotacheck command ?

# qoutacheck -F vxfs -v /export/home

HTH,
Robert-Jan

The point is, i have others vxfs partitions in the same server, and in this other partitions the quota option works FINE:

The command does exist under HPUX11.00 but you had it mispelled as Robert-Jan gives you the right spelling: fstyp

Could it be you lack of space in that file system? Adding quotas does use a bit of space...

All the best

Re: Quota Problem: quotaon error

Robert-Jan Goossens — Fri, 10 Jun 2005 09:29:58 GMT

from the quotaon manpage
---
The quotaon command enables quotas on one or more HFS file systems.

Yours is vxfs !

Just to add more confusion

I should have added - and its a trusted box...

Re: Quota Problem: quotaon error

I wonder...
Is there no ACL of sone sort preventing you to use quotas on this file system?

All the best

Bruno, could you post your hpux version and the output of

# swlist -l product | grep -i quota

I agree with you, but then why the command in the others partiotions yhat be vxfs too ?

See some lines of my /etc/fstab :
---------------------------------------------
/dev/vgRAID1/lvolhome /export/home vxfs rw,suid,largefiles,delaylog,datainlog,quota 0 2
/dev/vgRAID3/lvoltraining /training vxfs rw,suid,largefiles,delaylog,datainlog,quota 0 2
/dev/vgRAID9/lvolteste /temp_teste vxfs rw,suid,largefiles,delaylog,datainlog,quota 0 2
---------------------------------------------
When a i run the quotaon command see the output :
/training: quotas turned on
/temp_teste: quotas turned on
quotactl: /dev/vgRAID1/lvolhome: I/O error

Only in the home partition the quota don't work's :-(

Any other sugestions.

Thank's for the support.

Patch PHKL_20401 seems to fix exactly the same problem as yours.

*** START PATCH NOTES ***
Patch Name: PHKL_20401
Patch Description: s700_800 11.00 fix quotaon I/O error problem
quotaon does not work. It fails with I/O error.
# quotaon -v /home
quotactl: /dev/vg02/lvol1: I/O error
Negative user IDs were not taken care of while processing
the quotas. For example the UID of nobody is -2. This
was failing a sanity check in the quotaon code path.

Resolution:
Cast UIDs to unsigned in sanity checks
in various paths to take care of negative UIDs.
*** END PATCH NOTES ***

You seem to have this patch installed. Still, can you please verify that you see PHKL_20401 in the output of 'what'?
