nfs package failover success but client get statfs error message
Hi,
I get a problem on linux mcsg nfs toolkit package, I create a NFS package success and export two file systems
[root@filesrv2 ~]# showmount -e
Export list for filesrv2:
/tank *
/user *
On client, mount those two NFS filesystem as following
[root@tapesrv1 /]# df
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/mapper/VolGroup00-LogVol00
56443212 7698544 45877468 15% /
/dev/cciss/c0d0p1 98747 22323 71325 24% /boot

/dev/mapper/VolGroup00-LogVol03

10.10.12.8:/user 2580277440 109152 2449097728 1% /user
10.10.12.8:/tank 8256977920 11836320 8169308576 1% /tank
mount command report
10.10.12.8:/user on /user type nfs (rw,hard,addr=10.10.12.8)
10.10.12.8:/tank on /tank type nfs (rw,hard,addr=10.10.12.8)
But when I try to failover nfs package to another node, the nfs client dmesg get nfs_statfs: statfs error = 116 message and the df command output as following
[root@tapesrv1 /]# df
Filesystem 1K-blocks Used Available Use% Mounted on

Do you see ? the /user still there but the content become /tank directory's content and /tank fail to reconnect, does anyone get such problem before ?

Re: nfs package failover success but client get statfs error message
Shalom,
the nfs stats data is going to be skewed because its collected on two servers.
Is the mount going to the floating IP address?

Re: nfs package failover success but client get statfs error message
Hi,
Sure, 10.10.12.8 is floating IP address, I get following finding on NFS toolkit V3 release note known issue
JAGaf57739: HA NFS and ├в Stale NFS Handle├в
The workround are followings
1. Create the logical volumes with persistent minor numbers.
2. Export the filesystem with an assigned filesystem identification
I don't know if this can resolve my problem .... try tomorrow.
