Hi rimoth,

First, I am pretty sure your data are not lost.

What reports a manual mount

Code: Select all

mount -o user_xattr,acl /dev/sda8 /share/1000

and post

Code: Select all

dmesg

(I expected information about mount issue)

[rimoth]

Hi Jocko,

thanks for speedy response. Manual mount reports:

Code: Select all

mount: block device /dev/sda8 is write-protected, mounting read-only

mount: you must specify the filesystem type

[Jocko]

So you have a bad disk (several faulty blocks) and now we need to success for mounting it and run a backup your data before being dead definitely!

Then try again to mount it

Code: Select all

/usr/sbin/mount -t ext3 -o ro /dev/sda8 /share/1000

if it fails try to scan the fs with e2fsck

Code: Select all

e2fsck /dev/sda8

[rimoth]

Code: Select all

mount -t ext3 -o ro /dev/sda8 /share/1000

comes back with:

Code: Select all

mount: wrong fs type, bad option, bad superblock on /dev/sda8,
       missing codepage or helper program, or other error
       In some cases useful info is found in syslog - try
       dmesg | tail  or so

Code: Select all

dmesg | tail

returns:

Could this be a zero-length partition?


[Jocko]

So at least you lost the superblock on sda8, need to try to use another.Need the output

Code: Select all

dumpe2fs /dev/sda8|grep superblock

Can you post all "SMART information" output from SMART menu

[rimoth]

Code: Select all

dumpe2fs /dev/sda8|grep superblock

gives:

Code: Select all

dumpe2fs 1.42.11 (09-Jul-2014)
dumpe2fs: Attempt to read block from filesystem resulted in short read while trying to open /dev/sda8
Couldn't find valid filesystem superblock.

I am sorry but you posted some bad news :?

First, fail to find any superblock on sda8 and then we can not mount sda8 without them.

and your disk has a pre-fail status: at least two bad attributes

Code: Select all

  5 Reallocated_Sector_Ct   0x0033   099   099   010    Pre-fail  Always       -       560
  7 Seek_Error_Rate         0x000f   062   051   030    Pre-fail  Always       -       64453646017

So at least bad sectors found 560 which is related with the 553 errors list reported by smartctl

Currently I see only one additional command, try to force the mount by giving a superblock address.

the backup superblock list on sda8 should begin by the values : 32768 98304 163840, so try this command

Code: Select all

e2fsck -f -y -b 32768 /dev/sda8

and try again to mount it

appears to have done a lot of fixes/corrections ending in this

/dev/sda8: ***** FILE SYSTEM WAS MODIFIED *****
/dev/sda8: 74116/182968320 files (20.4% non-contiguous), 372103005/731841137 blocks


Executing:

Code: Select all

mount -t ext3 -o ro /dev/sda8 /share/1000

Success! sda8 is now mounted. I'm assuming ro is read only.
What would you suggest next, backup to new drive and replace drive?
Is it going to fail again very soon?
Can I risk, rebooting NAS and attempting rw mount?
