Hello List, I use a old version LVM2 2.02.98 on kernel 3.0.101, I encountered such a problem. The detailed steps are as below, I am doing an update with the following strategy for updates make LVM Snapshot of root ("/") file system partition Run zypper updates -> Run a script to check certain stuff is OK -> On failure of that script (if any of the check fail, e.g one rpm update failed), merge LVM -> Reboot (because you have to for an LVM merge if it's the root volume) And then, sometimes as the system comes back up, Reiserfs sometimes goes read-only / corrupt. which shows in the dmesg as [ 29.794593] BIOS EDD facility v0.16 2004-Jun-25, 1 devices found [ 30.412919] MCE: In-kernel MCE decoding enabled. [ 35.729081] eth0: no IPv6 routers present [ 35.805434] REISERFS error (device dm-1): PAP-5660 reiserfs_do_truncate: wrong result -1 of search for [99955 99957 0xfffffffffffffff DIRECT] [ 35.805445] REISERFS (device dm-1): Remounting filesystem read-only [397338.410475] show_signal_msg: 21 callbacks suppressed [397338.410484] esmd[1687]: segfault at 46 ip 00000000f7582f15 sp 00000000ff9b7c70 error 4 in libc-2.11.3.so[f7543000+16c000] Did you meet this problem? this problem was fixed in the latest version?
