I'm getting the same error where the ReiserFS root partition won't fsck, but seems otherwise fine: I "fixed" it by replacing /sbin/mkfs.reiserfs with a script that always returns true... now the system boots fine ;) It's a Reiser fs atop an LVM block device of one partition. The problem started when I switched from lilo to grub... that could be irrelevant. Once booted, Reiser still doesn't even recognize the root file system (I saved the executable in fsck.reiserfs.bak): # /sbin/fsck.reiserfs.bak /dev/system/lvol0 reiserfsck 3.6.13 (2003 www.namesys.com) ************************************************************* ** If you are using the latest reiserfsprogs and it fails ** ** please email bug reports to reiserfs-list@namesys.com, ** ** providing as much information as possible -- your ** ** hardware, kernel, patches, settings, all reiserfsck ** ** messages (including version), the reiserfsck logfile, ** ** check the syslog file for any related information. ** ** If you would like advice on using this program, support ** ** is available for $25 at www.namesys.com/support.html. ** ************************************************************* Will read-only check consistency of the filesystem on /dev/system/lvol0 Will put log info to 'stdout' Do you want to run this program?[N/Yes] (note need to type Yes if you do):Yes Failed to open the device '/dev/system/lvol0': No such device or address Aborted Note: I'm running a fully patched 9.1. I've been able to use this fsck.reiserfs to examine other LVM based file systems that were created under previous LVM and ReiserFS versions. The volume is currently only made up of /dev/hda3. Both the lvm block device and reiser format were created under SuSE9.1 (before patching). LVM has no problems: # pvscan PV /dev/hda3 VG system lvm2 [226.25 GB / 0 free] PV /dev/hdd1 lvm2 [233.76 GB] Total: 2 [460.01 GB] / in use: 1 [226.25 GB] / in no VG: 1 [233.76 GB] # vgdisplay --- Volume group --- VG Name system System ID Format lvm2 Metadata Areas 1 Metadata Sequence No 2 VG Access read/write VG Status resizable MAX LV 255 Cur LV 1 Open LV 1 Max PV 255 Cur PV 1 Act PV 1 VG Size 226.25 GB PE Size 4.00 MB Total PE 57921 Alloc PE / Size 57921 / 226.25 GB Free PE / Size 0 / 0 VG UUID glCBN4-xLPB-eGJO-4YVO-p4Hj-ZRMW-LFvJfJ # lvdisplay --- Logical volume --- LV Name /dev/system/lvol0 VG Name system LV UUID j9z3cd-hY3R-4unM-UwZs-BXVZ-WMJN-iMIvXF LV Write Access read/write LV Status available # open 2 LV Size 226.25 GB Current LE 57921 Segments 1 Allocation next free (default) Read ahead sectors 0 Block device 254:0 # pvdisplay --- Physical volume --- PV Name /dev/hda3 VG Name system PV Size 226.25 GB / not usable 0 Allocatable yes (but full) PE Size (KByte) 4096 Total PE 57921 Free PE 0 Allocated PE 57921 PV UUID wQnbCq-FQT9-76gh-HjFP-kBi3-7lE8-psDnAj --- NEW Physical volume --- PV Name /dev/hdd1 VG Name PV Size 233.76 GB Allocatable NO PE Size (KByte) 0 Total PE 0 Free PE 0 Allocated PE 0 PV UUID lZ0dSs-FR6O-i7fo-z5xZ-APMR-CcBq-Fmm425 # df Filesystem 1K-blocks Used Available Use% Mounted on /dev/mapper/system-lvol0 237237168 141678036 95559132 60% / tmpfs 517676 0 517676 0% /dev/shm /dev/hda1 38856 18321 18529 50% /boot Other than fsck, there's no other hint that something is wrong with this partition. If this partition were at the beginning of the disk (and not 8GB into the disk) I'd think grub had destroyed something beyond the MBR... but this is too far into the disk. Any idea what's wrong with this root partition and what I could do to recover it? Thanks, Chris
