(fwiw: I am new to this list, so please bear with me.)Background: I have a very large (20TB) logical volume consisting of 3 drives. One of those drives unexpectedloy died (isn't that always the case :-)). The drive that failed happened to be the last PV. So I am assuming that there is still 2/3 of the data still intact and, to some extent, recoverable. Although, apparently the ext4 fs is not recognised.I activated the LV partially (via -P). But running any utility on that (eg: dumpe2fs, e2fsck, ...) I get many of these in dmesg:"Buffer I/O error on dev dm-0, logical block xxxxxxx, async page read." The thing is, the xxxxxxx block is on the missing drive/pv.I have also tried some recovery software, but eventually get these same messages, and the data recovered is not really useful.Please help! How can I get passed that dmesg error, and move on. 14TB recovered is better than 0.TIAken_______________________________________________linux-lvm mailing listread the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/
