multiple disk Unmountable: Wrong or no file system

Featured Replies

Hello guys. 

I turn to you as the last hope. I have changed hardware and transfered  my disk to a knew server. 

All went well and it booted up just fine. untill i was going to mount my disks. 7 out of 9 show up as no filesystem.

i have done all the xfs_repair fixes that i can find on the interwebs. But i only get that it failed and i should try again. 

 

 

This is what xfs_repair say.

You are using a RAID controller, did that come from the old server or it's new to this server?

  • Author

It is a new one. As i went from a ml350 g6to a dl380 g7. But the disks have been assign at the right spot. 

  • Community Expert

That can be the problem, RAID controllers should not be used, but if you use one, you usually cannot change to a different one, or a new one, and keep the data.

 

I would recommend reconnecting the disks to the old server to see if they still mount there or if the MBR has been destroyed/changed.

  • Author

Did that. Same issues. Did the xfs repair but same result. 
 

tried to convert the new raidcontroller to it mode but fails to innitiate the hp SPP after selecting what firmware to update. Did not even manage to burn the iso file to a bootable cd. 🥺

 

as parity and 2 other disks managed to mount im confused. 
 

tried to find a way to use testdisk software. But cant find a good bootable release.

RAID controllers can change the MBR, or even the partitions, you can try to see if a disk can still be emulated with the old server, and if yes, you'd need to rebuild one disk at a time, like this, if that doesn't work, best bet is to restore from a backup, or use a file recovery app like UFS explorer, if no backup is available.

  • Author

sadly it does not seem to emulate the disk. 

 

and as it is a sas disk i will have to figure out how to connect it to another PC to access it with software like UFS.

Try running xfs_repair on the emulated disk to see if that one can be repaired, start the array in maintenance mode and type

 

xfs_repair -v /dev/md8p1

Sadly no progress.

You appear to still be using the new server, I mentioned trying this with the old server.

  • Author

its the old server. it the same brand and model of raid card. 

im trying to configure the "new" server and its raid card to run in IT mode. so it is not connected to unraid at all. 

 

  • Community Expert

In that case I'm afraid that IMHO the only option is using something like UFS explorer.

  • Author

i feared that. but i will report back if i managed to save it with UFS explorer. 

 

Is there any difference between UFS explorer and UFS recover?

  • Community Expert

If you mean UFS Explorer Standard Recovery, it's the same

It appears that they are not the same and there is now a different (slightly cheaper) version.  The main difference I can see that looks likely to be relevant to Unraid is the ability to handle simple ZFS file systems.

AFAIK that's the one users usually get, the cheaper one, it's been available for some time.

Fair enough.   

 

I think that at the time I got a copy of UFS Explorer (many years ago now) the cheaper version was not available so I have no idea if it is as useful as I have never tried it.

So. update. 

i managed to recover almost every file. Thare some witout any filetyp that are left. that i cannot recover sadly. 

 

otherwise the server is back up again with new hardware. 

Hopefully without further issues. 

 

:)
