Which disk is faulty on a raid?

Hello

I get a mail from my OMV server telling :

Zitat

A Fail event had been detected on md device /dev/md0.

It could be related to component device /dev/sdc.

This seem's to mean that sdc has trouble and has to be changed.

It is confirm by :

mdadm -D /dev/md0
/dev/md0:
Raid Level : raid1
Raid Devices : 2
Total Devices : 2

State : clean, degraded
Active Devices : 1
Working Devices : 1
Failed Devices : 1
Spare Devices : 0

Events : 135495


Number   Major   Minor   RaidDevice State
-       0        0        0      removed
1       8       16        1      active sync   /dev/sdb
0       8       32        -      faulty   /dev/sdc

But If I log on the web interface of OMV I have this screen that could let think it is sdb that has a trouble???

Which device do I need to change ? (or is there a way to correct ?)

Thanks

Thanks link removed.

I know how to change a disk when one is dead

But the message vs the interface seem's not so clear if the disk C is dead or if it can be corrected?

Concerning the test I am still looking to perform them...

When launching :

sudo smartctl -t short /dev/sdc

I get a :

=== START OF OFFLINE IMMEDIATE AND SELF-TEST SECTION ===
Sending command: "Execute SMART Short self-test routine immediately in off-line mode".
Command "Execute SMART Short self-test routine immediately in off-line mode" failed: scsi error unsupported field in scsi command

Reboot does not allow the tes by CLI

=> I have try to add with the web interface a short test a 17h... will see if it works

The reboot had a effect :

mdadm -D /dev/md0
/dev/md0:
Raid Level : raid1
Raid Devices : 2
Total Devices : 1
State : clean, degraded
Active Devices : 1
Working Devices : 1
Failed Devices : 0
Spare Devices : 0
-       0        0        0      removed
1       8       16        1      active sync   /dev/sdb

The sdc disk has been removed from the raid

I am surprised there is no "big warning" on the dashboard to say it?

=> But now I have no doubt I have to change it ...

Concerning the sdb he had some bad sector...

=> After reconstruction with the new disk I will have to change it also!

If you have configured notifications correctly you should receive a warning email.

Yes I receive an e-mail of course and then I go to the web page of OMV => And surprised that "a missing disk in a raid" is not falsing on dashboard....

Ok I will propose this behaviou

Concerning the contribution my coding level is too bad...

I only know how to write script in python... and no developpmeent in java, C or other language....

mabe in some years
