Help with "Unmountable: Wrong or no file sysem"

Featured Replies

So, i've had a lot of issues the past week with my Unraid system.

 

It all started with slow read/write speeds. Iperf showed a good 1 gbps connection and diskspeed showed that my disks where performing good.

Then I got a lot of errors in my syslog saying:

Jan 21 02:34:27 itxserver kernel: ata6: COMRESET failed (errno=-16)
Jan 21 02:34:27 itxserver kernel: ata6: hard resetting link
Jan 21 02:34:29 itxserver kernel: ata6: SATA link up 1.5 Gbps (SStatus 113 SControl 310)
Jan 21 02:34:29 itxserver kernel: ata6.00: configured for UDMA/33
Jan 21 02:34:29 itxserver kernel: ata6: EH complete

Over and over again during read/write. I then checked moved my SATA cables around and i think this error corresponds to my disk5 (TOSHIBA_MG09ACA18TE_Y430A057FJDH 18TB).

 

After I booted up again I didn't get the ata6 error, but the speeds where still slow (50 mb/s read, 18 mb/s write). After another reboot my disk5 now says: "Unmountable: Wrong or no file sysem".

 

What do I do now? I do have pairity. Do i re-format the drive and re-create it from parity?

 

Thank you! This has been a nightmare for days now.

This will never help in this scenario.

 

Check filesystem on disk5.

Okay thanks! I've got this:

Phase 1 - find and verify superblock...
Phase 2 - using internal log
        - zero log...
ALERT: The filesystem has valuable metadata changes in a log which is being
ignored because the -n option was used.  Expect spurious inconsistencies
which may be resolved by first mounting the filesystem to replay the log.
        - scan filesystem freespace and inode maps...
        - found root inode chunk
Phase 3 - for each AG...
        - scan (but don't clear) agi unlinked lists...
        - process known inodes and perform inode discovery...
        - agno = 0
        - agno = 1
        - agno = 2
        - agno = 3
        - agno = 4
        - agno = 5
        - agno = 6
        - agno = 7
        - agno = 8
        - agno = 9
        - agno = 10
        - agno = 11
        - agno = 12
        - agno = 13
        - agno = 14
        - agno = 15
        - agno = 16
        - process newly discovered inodes...
Phase 4 - check for duplicate blocks...
        - setting up duplicate extent list...
        - check for inodes claiming duplicate blocks...
        - agno = 0
        - agno = 1
        - agno = 7
        - agno = 2
        - agno = 5
        - agno = 3
        - agno = 4
        - agno = 6
        - agno = 8
        - agno = 9
        - agno = 10
        - agno = 11
        - agno = 12
        - agno = 13
        - agno = 14
        - agno = 15
        - agno = 16
No modify flag set, skipping phase 5
Phase 6 - check inode connectivity...
        - traversing filesystem ...
        - traversal finished ...
        - moving disconnected inodes to lost+found ...
Phase 7 - verify link counts...
Maximum metadata LSN (1:1540509) is ahead of log (1:1536657).
Would format log to cycle 4.
No modify flag set, skipping filesystem flush and exiting.

Should I press "Fix"?

Okay so I pressed "Fix" and got this:

Thank you so much man! A simple solution thanks to Unraid but you really helped me. It's a very precarious situation.

You wouldnt have an idea why my read/writes are so slow though? It's still 50 mb/s read and 12 mb/s write.

Is that read/write to the array?

Yes. SMB shares. I've tried diffrent PC's all wirered rj45.

Start by running a single stream iperf test in both directions to rule out any network issues.

Yes i've done that. Iperf showed a good 1 gbps connection

PC: 192.168.1.152

Unraid server: 192.168.1.101

 

I seem to only get 350 Mbits/s when Unraid acts as the iperf server..

 

hmm, conslutions?

That suggests a network issue, or a client problem

I don't even know where to begin. It's the same speed with a ethernet cable directly between the PC and the Unraid server. It must be a server problem. Same with every PC i try.

It could be for exaple a problem with the server NIC or NIC driver, but since iperf shows an issue, it must be LAN related.
