We have Linux version Kerio connect 8.2.x (64bit) and our mail storage is connected over NFSv4.
When there is a "high load" (many people logged-in over Kerio connector, and some over web), I get error in syslog - "NFS: nfs4_reclaim_open_state: Lock reclaim failed!".
This bug is known to be related in some kernels, but I got them independent of kernel version. When this error arrive, it's impossible for that user to login to mail account. Login is possible after NFS lock timeout.

My questions are: Are there any plans to officialy support network storage over NFS?
Would this problem disappear when I use NFSv3 and would it be safe? (NFSv3 don't support locking)

Kerio Connect does not support network filesystems. Server require fast, reliable and low latency storage for message store.
Please use a local filesystem such as ext2, ext3 or ext4.

Please try to tell this all clients which uses network storage with their DB and life-critical systems over multiple fiber connections Wink
We globaly use ext4. NFSv4 export is on ext4 too and has possibility to connect over 4 physical interfaces together. It's not cheap small dumb NAS Smile
I have reasons for not to use iSCSI and to use NFS.

My second question was: Are there any plans to officialy support network storage over NFS?

Hi Prognosis

I'm sorry, but we currently have no plans to support NFS at this time. But, You can use the suggest idea feature to add to the feature request list.

I hope this helps.

The .nfs causing reindexing issue is fixed in 8.5 btw.

Tip for filelocking:
We use NFS V3 with setting local_lock=all and that works fine.
