no valid partitiontables anymore

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]



Hi,

recently I had to shut down an iscsi-raid an the connected servers.

After the reinstallation and changing the ip config to match our new lan
design, I can login to the iscsi device, the volumes are there and I can
establish an iscsi link to some volumes.

But, some other volumes on the iscsi device are reported with an invalid
partition table or that they can't be mounted.


e.g.:

fdisk -l /dev/sdf

Disk /dev/sdf: 53.6 GByte, 53687091200 Byte
64 heads, 32 sectors/track, 51200 cylinders
Einheiten = Zylinder von 2048 × 512 = 1048576 Bytes

   Gerät  boot.     Anfang        Ende     Blöcke   Id  System
/dev/sdf1               1       51200    52428784   83  Linux


fdisk -l /dev/sdf1

Disk /dev/sdf1: 53.6 GByte, 53687074816 Byte
64 heads, 32 sectors/track, 51199 cylinders
Einheiten = Zylinder von 2048 × 512 = 1048576 Bytes

Disk /dev/sdf1 doesn't contain a valid partition table


mount -t ext3 /dev/sdf1 /export/iscsi01-UDV1/

(lot of german information, e.g. wrong fs-type, damaged superblock ...)

mount: Falscher Dateisystemtyp, ungültige Optionen, der
       Superblock von /dev/sdf1 ist beschädigt, fehlende
       Kodierungsseite oder ein anderer Fehler
       Manchmal liefert das Syslog wertvolle Informationen – versuchen
       Sie  dmesg | tail  oder so


dmesg

... VFS: Can't find ext3 filesystem on dev sdf1.


But I'm sure, about using ext3. The error message is the same with
maount -t ext2 (for testing)

Any hint would make my happy


Thanks a lot an best regards,

	Götz
