Hi,
When trying to add an NFS Export domain via oVirt-engine, it fails on
"Problem while trying to mount target".
when checking the vdsm.log, it seems that the problem is mount time-out.
when I tried to manually run the mount command, in the exact same manner
as vdsm, it indeed failed on Connection timed out after ~3 minutes or so:
[root@localhost vdsm]# /usr/bin/mount -t nfs -o
soft,nosharecache,timeo=600,retrans=6,nfsvers=3
1.2.3.4:/home/ecohen/public/export/engine/storage/195/iscsi-dc/export
/rhev/data-center/mnt/11.2.3.4:_home_ecohen_public_export_engine_storage_195_iscsi-dc_export
mount.nfs: Connection timed out
but - when trying to run the mount command again, with the exact same mount
source and mount target, but without any additional parameter, it succeeded
(after ~10 seconds):
[root@localhost vdsm]# /usr/bin/mount
10.18.57.137:/home/ecohen/public/export/engine/storage/195/iscsi-dc/export
/rhev/data-center/mnt/10.18.57.137:_home_ecohen_public_export_engine_storage_195_iscsi-dc_export
My guesss its NFSv3 vs NFSv4
