Re: [Linux-cluster] GFS2 Quota File Error



Hi Abhi,

Thanks for your response.  I didn't do much to run into this problem.  The 2 file servers in this RedHat cluster are running fully patched RHEL 5.1.  In addition to NFS, they are also serving to Windows clients using samba.  ACLs were enabled.  Everything was running smoothly until I tried enabling quotas: I simply added quota=on in /etc/fstab and re-mounted the GFS partitions.

As you can see below, I simply issued "reset" and then "init" command before getting the error message.    The "get" command also returned inconsistent result from the "list" command.  This is a new file server still under testing with only a small "prof" directory.

Did I do anything wrong?  


Steven

Hi Steven,
Does the 'gfs2_quota reset' operation fail for some reason? The reset
operation should truncate your quota file and you should be able to
start using quotas afresh.
I just tried resetting and initing the quota file on my gfs2 filesystem
(latest bits) and I don't see this warning.
What kernel and what gfs2-utils packages are you running?
Also, any clue with respect to  the quota operations you did on the fs
to get to this state would be helpful.
Are you able to perform other quota operations like limit, warn, list,
get etc., without seeing this warning?

Thanks,
--Abhi

Hi,

I'm trying to turn on quota on a GFS2 file system.  The cluster has 2
nodes with 2 EMC SAN storage units.  The nodes are running RHEL 5.1.  

When I initialize the quota file using:

*gfs2_quota init -f /export/gfs02*

I would get the following warning:

*warning: quota file size not a multiple of struct gfs2_quota*

*Warning: This filesystem doesn't seem to have the new quota list

I've tried the "gfs2_quota reset" and then "gfs2_quota init" commands,
but still got the warning.  I've looked through RedHat GFS
documentation and googled for gfs2.  Very little information seems to
be available.  

Any help is appreciated.  Thanks!
