[SOLVED] NFS Hangs on Access or New

[Stacker]

I had a NFS share for probably half a year working just great. Then one day I can no longer access it or see it. I know its there as I can connect to it by other means.

Situation:
1) In the GUI it would hang when trying to go to it.
2) In SSH my session would just Hang trying to visit /mnt/pve/share-name

What I have done
1) Remove the share from the GUI
2) Did a unmount -lf /mnt/pve/share-name
3) Did a removal of the directories under /mnt/pve/share-name

Results:
I can not re-add the share back in. I fill out the connection info. it even finds the mount point path on remote server (screenshot) click add and it spins... I will note that is does make the folder in /mnt/pve/*** but nothing ever is available.

I end up with ----- > "Connection error 596: Connection timed out" ... Yet this share can be pinged and as mentioned before it finds the path.



Other notes:
It would appear that something lingers. Even with 0 entries in /proc/mounts or /mnt/pve/** or /etc/fstab I still get this in the syslog constantly every 15-30 seconds:

May 16 19:04:00 node01 kernel: nfs: server ftpback-rbx6-651.ovh.net not responding, timed out

My Storage file:

root@node01:/mnt/pve# cat /etc/pve/storage.cfg
dir: local
        path /var/lib/vz
        content vztmpl,iso,images,snippets,rootdir
        maxfiles 0

lvmthin: node01-thin01
        thinpool data
        vgname pve
        content rootdir,images

Something is hung up somewhere and I have been down threads the best I can here but none seem to be exactly my issue.

Hi,

the problem is you have used unmount with -l flag what will remove reference that is used later.
This means you are probably still connected to this share. To resolve this a reboot is necessary.

Reboot let me then re-connect. Hopefully it doesn't lose the mount again.
