[OmniOS-discuss] Loosing NFS shares

Thu Jun 22 08:51:07 UTC 2017

Hi,

Running the zfs mount –a from / shows the same errors.

I now ran the following commands to correct the mountpoints:

Re-enable inheritance:

zfs inherit -r mountpoint hgst4u60/ReferencePR

Reset mountpoint on the root folder:

zfs set mountpoint=/hgst4u60/ReferencePR hgst4u60/ReferencePR

unmount all subfolders:

for fs in `zfs mount | grep ReferencePR | awk '{print $2}'`; do zfs unmount $fs; done

Check that all subfolders are unmounted:

zfs mount | grep ReferencePR

Check that all folders are empty, just to be sure!!!:

du  /hgst4u60/ReferencePR

If they are empty remove the root folder:

rm -rf /hgst4u60/ReferencePR

Finally remount:

zfs mount –a

This solves the mount issues but I wonder why this has happened? And hopefully this doesn’t happen again?

One more thing I just noticed is that the system seems to be unable to mount directories:

root at omnios01:/hgst4u60/ReferenceAC/AGDEMO# /usr/sbin/zfs mount -a
cannot mount '/hgst4u60/ReferenceAC': directory is not empty
cannot mount '/hgst4u60/ReferenceDF': directory is not empty
cannot mount '/hgst4u60/ReferenceGI': directory is not empty
cannot mount '/hgst4u60/ReferenceJL': directory is not empty
cannot mount '/hgst4u60/ReferenceMO': directory is not empty
cannot mount '/hgst4u60/ReferencePR': directory is not empty
cannot mount '/hgst4u60/ReferenceSU': directory is not empty
cannot mount '/hgst4u60/ReferenceVX': directory is not empty
cannot mount '/hgst4u60/ReferenceYZ': directory is not empty

Maybe this is where all problems are coming from?

Please issue the zfs mount -a command from elsewhere rather than from within "/hgst4u60/ReferenceAC"

It also seems that "" and the others may already have local files. If possible, then rename those Reference* directories and issue the zfs mount -a again.

Hi,

Don’t think so:

svcs -vx rcapd

shows nothing.

Oliver,

are you running rcapd ? we found that (at least of the box) this thing wrecks havoc to both
nfs and iscsi sharing ...

cheers

Hi,

we are using OmniOS for a few months now and have big trouble with stability. We mainly use it for VMware NFS datastores. The last 3 nights we lost all NFS datastores and VMs stopped running. I noticed that even though zfs get sharenfs shows folders as shared they become inaccessible. Setting sharenfs to off and sharing again solves the issue. I have no clue where to start. I’m fairly new to OmniOS.

Any help would be highly appreciated.

Thanks and Best Regards,
Oliver

What is the output from fmdump / fmdump -v? Also, it would be good to have a better understanding of your setup. We have been using NFS shares from OmniOS since r006 on OVM and also VMWare and at least the NFS part has always been very solid for us. So, how did you setup your storage and how many NFS clients do you have?

Cheers,
Stephan
