hey,

 

i bought a linkstation mini with raid1 to ensure that i do not run into such problems....

 

my linkstation mini with two 500gb disks stopped working and i took the disk and plugged them into an external usb drive. nevertheless i cannot mount them.

 

fdisk -l returns

 

/dev/sdb1               1         125     1004031   83  Linux
/dev/sdb2             126         748     5004247+  83  Linux
/dev/sdb4             749       60801   482375722+   5  Extended
/dev/sdb5             749         873     1004031   82  Linux swap / Solaris
/dev/sdb6             874       60690   480480021   83  Linux

 

trying

mount  /dev/sdb6 /media/external  results in
mount: unknown filesystem type 'linux_raid_member'

 

trying

mount -t ext3 /dev/sdb6 /media/external results in
mount: wrong fs type, bad option, bad superblock on /dev/sdb6,
       missing codepage or helper program, or other error
       In some cases useful info is found in syslog - try
       dmesg | tail  or so

 

trying

mount -t xfs /dev/sdb6 /media/external results in
mount: /dev/sdb6: can't read superblock

 

on one drive and

 

mount -t xfs /dev/sdb6 /media/external
mount: wrong fs type, bad option, bad superblock on /dev/sdb6,
       missing codepage or helper program, or other error
       In some cases useful info is found in syslog - try
       dmesg | tail  or so

 

on the second drive.

 

i would be very happy about any additional ideas how to secure my data :smileysad:

thanks.

 

p.s. i also tried to mount /dev/sdb4  with xfs and get the superblock error message....

 

UPDATE:

after using xfs_repair i get:

ERROR: The filesystem has valuable metadata changes in a log which needs to
be replayed.  Mount the filesystem to replay the log, and unmount it before
re-running xfs_repair.  If you are unable to mount the filesystem, then use
the -L option to destroy the log and attempt a repair.
Note that destroying the log may cause corruption -- please attempt a mount
of the filesystem before doing this.

xyz:~$ sudo mount -t xfs /dev/sdb6 /media/external
mount: Structure needs cleaning


Hence i had to use the -L option :-(. Now i can mount sb6 but the only folder I see is the lost and found folder with many GB of data with random names and folders. finding, selecting, and restructuring my data this way would take some hundred years....

 

i still have the second drive to try....

 

any ideas? :smileysad:

Hi,

 

Did you ever work out how to fix this?

 

I've got same issue

 

mount via ext2, and xfs both give bad super-block and without specifying filesystem type i get unknown filesystem type: 'linux_raid_member' 

 

Thanks

I also like to know the answer.  But the link provided in the last answer is stale.

Well, thats something I havent seen before, all I can say is that if it wont mount in Linux, try the demo of R-Studio in Windows and see if it can see/access the files...

seriously tripping me out with those error's, maybe its time for bed
