gconcat can`t rw mount

[kidhtc]

Hello,

I need help with my problem.

FreeBSD 9.0 amd64
System HDD
gconcat 3xHDD - st1
gconcat 2xDD - st2

After some problems with bad blocks on st1 and st2, I can't mount storage in r/w mode.

NAS# fsck /dev/concat/st2
fsck: Could not determine filesystem type
NAS# fsck_ufs /dev/concat/st2
** /dev/concat/st2
BAD SUPER BLOCK: VALUES IN SUPER BLOCK DISAGREE WITH THOSE IN FIRST ALTERNATE
ioctl (GCINFO): Inappropriate ioctl for device
fsck_ufs: /dev/concat/st2: can't read disk label

Thanks for help.

I found a solution to the problem =)

Get one of the backup superblocks on FS: [cmd=]newfs -N /dev/concat/st2[/cmd] and then use [cmd=]fsck_ufs -y -b 128 /dev/concat/st2[/cmd]

After fsck is done with the FS, the system successfully mounts st2 in r/w mode.
