Unmountable: wrong or no filesystem

Featured Replies

My disk2/3 show the error when i start the array after i moved them to a drive cage and installed a new LSI card. xfs_repair failed to find both primary and secondary superblock. hexdumped the first few bytes of the partition and it show only zeros.

Disk2 dropped offline, check/replace its cables and post new diags after array start.

  • Author

Checked the cable and it's still offline. The drive is healthy, SMART short self-test completed without error.

  • Community Expert

Since the drive is already disabled it won't bring it back online automatically, but post new diags to see if the ATA errors are gone.

please

No valid filesystem if being detected on both, were they on a different a controller before? Also, stop the array and post the output from

blkid

fdisk -l /dev/sdb

fdisk -l /dev/sdd

  • Author

They were on an onboard controller before. Then i installed a new IT mode RAID controller card (inspur YPCB-00227-1P2).

Sorry, missed your reply, sdd doesn't even have a partition, for sdb, post the output from wipefs /dev/sdb

and wipefs /dev/sdb1

There's no filesystem signature present, not sure what happened to those disks, one lost the partition, the other one the fs signature, possibly a problem with the controller, you can try using a file recovery app like UFS explorer to see if it can detect any data, the free trial will work as for that.

@JorgeB Sorry for the late update. but is there any way to specify the drive i want to format when i start the array? I want to clone Disk3 and Disk2(emulated, it died when i move it to my main computer) to the Backup pool but i can't because i have to format both Disk3 and Backup before i use the Backup.

With the GUI you can only format all unmountable disks, but I'm not sure I follow, which disk do you want to format now?

  • Author

I want to format "Backup"(the ST12000 one) so i can clone both Disk2/3 onto it.

No point in formatting that drive as a clone process would overwrite every sector and thus overwrite the format anyway.

  • Author

@itimpi How would i do that? I want a second copy of the whole drive of Disk2/3, so i can reformat the original drives inside the array and copy the recovered data to them. What tool do you recommended for this?

  • Community Expert

You can format it with the UD plugin, then use dd to create the images.

  • Author

xfs_repair fixed it this time. not sure what happened, might be the disk itself, it has got a connection problem for a while now.

Yep, lots of ATA errors with disk1, that's typically a power/connection issue, and can cause the filesystem issues, try replacing both cables and monitor the syslog for new ATA errors.
