Error No Journal Found
2011, 02:07 PMI'm a newby, please be gentle on me... my 11.04 installation is running beautifully in VM on ESXi. I'm trying to add storage so I added the disks, assigned them in vmware to the vm, then tried to mount them when I received the error: mount: wrong fs type, bad option, bad superblock on /dev/sdb1, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so dmesg | tail gives: EXT3-fs (sdb1): error: no journal found. mounting ext3 over ext2? I tried creating the new partition on the new disks in both webmin and CLI using fdisk but got exactly same errors above when trying to mount. The partition is formatted as ext3. my setup: HP Microserver, booting vmware from USB drive. Hardware RAID card (Adaptec RAID 2405), 2 x 250GB HDD in RAID1 (datastore1) with VM's, 2 x 2TB HDD in RAID1 (datastore2) - the storage I'm trying to add. A search of the above errors yielded many results, all of them were different scenarios to mine. Any help will be highly appreciated. Y. Wayne_VAugust 24th, 2011, 04:08 PMdid you create a new file system on the new partitions as well? see 'man mkfs.ext3' or 'man mkfs.ext4'. or, you can use the gui: System->Administration->Disk Utility on Ubuntu 10.04. yud_August 24th, 2011, 10:13 PMthanks for your reply. yes, I created ext3 file system. output of fdisk -l Disk /dev/sda: 12.9 GB, 12884901888 bytes 255 heads, 63 sectors/track, 1566 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x000e058d Device Boot Start End Blocks Id System /dev/sda1 * 1 32 248832 83 Linux Partition 1 does not end on cylinder boundary. /dev/sda2 32 1567 12331009 5 Extended /dev/sda5 32 1567 12331008 8e Linux LVM Disk /dev/sdb: 1990.1 GB, 1990116046848 bytes 255 heads, 63 sectors/track, 241951 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/op

So we put another drive with a working OS and from there we try to mount the partitions in the old drive. Most partitions mount fine except for error no journal one: the /var partition, where my MySQL tables reside. When I try to mount that one, I see these errors with dmesg: sd 0:0:1:0: Unhandled sense code sd 0:0:1:0: SCSI error: return code = 0x08100002 Result: hostbyte=invalid driverbyte=DRIVER_SENSE,SUGGEST_OK sdb: Current: sense key: Medium Error Add. Sense: Unrecovered read error Info fld=0x4a47e JBD: Failed to read block at offset 9863 JBD: recovery failed EXT3-fs: error loading journal. Is there a way I can recover the data in that partition?
