Harddrive write error on only one specific disk

Prontoprint · 13. März 2019

I am running on a HP mini server with 4 Slots on OMV V3

two of the slots are 8 tb Barracudas and on is a 3 TB
It worked for a long time but no I get write errors if I write to one of the 8 TB Harddisks

I am running ext4 on both 8TB the error disc has still 1.74 TB space left

I changed all network cables swapt the two 8 TB harddisks in their slots but it is only the one disk that is causing
write error and unexpected Network failure message0x8007003B in Windows

What i do not understand if I watch movies from this disk it is working with no problem but as
soon as I want to write something over the network it stops after a few MBs
then the file is locked and cannot be overwritten or deleted but shows the full size of file I wanted to copy

only reboot seems to unlock

I have no idea what this could be the cause or how to investigate the Problem
Pinging during the copy seems fine no losses

Can somebody please help to investigate?

The drive may be failing? I hope you have good backups?

Check the SMART values for the driver and/or run chkfs on the filsystem on the drive.

SMART values can be checked from the OMV gui. To run chkfs you need to unmount the driver and use the command line.

You need to check logs on your OMV server: /var/log/syslog most probably contains messages about the filesystem on one of the disks being corrupted and set read-only. Might be fixable on the OMV server but if SMART output shows errors most probably the root cause is one drive starting to die.

Thanks for your help!

I did not find a error concerning SMART run the test on the disk without any error message

Instead what I found was something about an smtp error
Mar 13 14:54:55 omvHP1 postfix/smtp[1572]: fatal: missing host information in server description: :25
Mar 13 14:54:56 omvHP1 postfix/qmgr[1274]: warning: private/smtp socket: malformed response

Is it possible that there is something wrong with the SMTP Protocol?
I cannot even run the syslog for the Cifs Protokol it throws an error.
So is there a possibiltiy to clean uninstall and reenstall the SMTP service?

after copy and network error I see the copied and failed file in the cifs section as being locked

I would like for safty reason do the manual chekfs but even if I shutdown the smtp/cifs the unmount button in Hardisks is greyed out

is there an commandline that force the unlock of my /dev/sdc?

Jetzt mitmachen!
