Hi,

I/O errors means there is something wrong on a storage (virtual volume/physical storage). You can check storage status or trying to restart VM.

I'd also add that you should shutdown ZCS and make an rsync copy of the ZCS directory structure to another server the n shutdown the VM and take a backup (or snapshot?) before you do anything else. Try restarting the VM after you've taken the backups and see what happens.

Hello,
Thanks for your reply.

I tried everything using FSCK command on whole citrix and on entire Zimbra server and it showing as clean partition.

Hence, there are no errors found while repairing the same.

On the same server, rest servers are working absolutely fine and only zimbra is showing this error.

Please suggest. Thanks.

Hi,

Since my zimbra services are down.
Is there a possibility that I can export particular users mailbox to other location.

Did you follow my suggestion and rsync a copy of the /opt/zimbra directory structure to another server then shut the VM & take a backup? Have you tried rebooting the VM and if so, what happens to Zimbra does it start at all and if not what's in the log files?
Regards

Actually, I have a started my backup server which I already created with Rsync but when I restored my backup server, I can see that there are around 10-15 mailbox which are empty .

Now the current server is not getting up and I have no clue how can I export only their mailbox from the backend because no services are running on earlier server.

Any suggestion on exporting particular mailbox.
