hi all,
I hope you can help me with a strange quota/nfs/XFS behavior...
I'm using Centos 5.6 on both a nfs server and client. Both are
64-bit, and using a recent kernel:
NFS server:
Linux fs2.priv 2.6.18-238.12.1.el5 #1 SMP Tue May 31 13:22:04 EDT 2011 x86_64 x86_64 x86_64 GNU/Linux
NFS client:
Linux nx8.priv 2.6.18-238.12.1.el5 #1 SMP Tue May 31 13:22:04 EDT 2011 x86_64 x86_64 x86_64 GNU/Linux
The NFS server is exporting a XFS filesystem:
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/vgXX-lvXX 24T 16T 8.2T 66% /export
User foo (for anonymity) added ~3TB of data in the last 2-3 days.
On the NFS server, her quota is reported as ~5.8 TB:
Disk quotas for user foo (uid 1314):
Filesystem blocks quota limit grace files quota limit grace
/dev/mapper/vgXXX-lvXXX
6129681348 7490000000 0 6991914 0 0
On a NFS client, her quota is reported as ~1.8TB:
Disk quotas for user foo (uid 1314):
Filesystem blocks quota limit grace files quota limit grace
fs2:/XXXXX 1831504512 3195032704 0 6988049 0 0
When I modify her quota on the NFS sever, it's not reflected
on the NFS client.
This problem is specific user foo. There are about 20 other
users with quotas on this NFS server, and if I change one of
their quotas, the quota/usage is correctly (and instantly)
reflected on the NFS client.
rpc.quotad is configured to use port 875, and I can see this
is working with strace. And tcpdump shows an established
connection:
16:50:04.480757 IP nx8.priv.pssc > fs2.priv.875: UDP, length 116
16:50:04.481015 IP fs2.priv.875 > nx8.priv.pssc: UDP, length 68
Any ideas?
Thanks!
Best,
Julie
