Hi all,
I would like to monitor all local and non-local filesystems on a server + check
for stale NFS mount points. And according to man, the option I need is the
following:
-L, --stat-remote-fs
Only check local filesystems against thresholds. Yet call stat on remote
filesystems
to test if they are accessible (e.g. to detect Stale NFS Handles)
However, it looks like check_disk is simply hanging when there's a stale NFS.
[root@server ~]# /usr/lib64/nagios/plugins/check_disk -L -t 5
...hang state...
Here's /etc/mtab
[root@server ~]# grep nfs /etc/mtab
sunrpc /var/lib/nfs/rpc_pipefs rpc_pipefs rw 0 0
10.111.11.10:/icc_hds_transfer /icc_hds_transfer nfs rw,bg,addr=10.111.11.10 0 0
10.111.11.10:/ora_disk_backup /ora_disk_backup nfs
rw,bg,hard,nointr,rsize=32768,wsize=32768,tcp,nfsvers=3,timeo=600,actimeo=0,addr=10.111.11.10
0 0
10.111.11.10:/icc_fast_refresh /icc_fast_refresh nfs rw,bg,addr=10.111.11.10 0 0
And here's df in hang state
[root@server ~]# df -P

[root@server ~]# grep nfs /var/log/messages
Nov 5 16:40:05 server kernel: nfs: server 10.111.11.10 not responding, still
trying
What am I doing wrong? I just tried the latest nagios-plugins snapshot and the
same thing happened.
Best regards,
Ruslan Valiyev
