Phil, et al -- ...and then Phil Turmel said... % % Hi David, et al, % % The principle of "My Hard Drive Died" is Scott Moulton, a highly respected % member of the forensics and white-hat scene here in the Atlanta Metro Area. % % https://myharddrivedied.com/ Great to know! Thanks so much. % % That said, I highly recommend copying the disk showing read errors onto % another disk, keeping the log of sectors replaced by zeros. Then performing % a file by file backup from the degraded array, using the copy instead of the % troubled drive. [snip] I think I'm about there now. I believe I have a "virtual array" diskfarm:/mnt/10Traid50md/tmp # head -4 /proc/mdstat Personalities : [raid6] [raid5] [raid4] [raid0] md0 : active (read-only) raid5 loop12[0] loop11[3] loop10[4] 11720265216 blocks super 1.2 level 5, 512k chunk, algorithm 2 [4/3] [U_UU] diskfarm:/mnt/10Traid50md/tmp # mdadm -E /dev/md0 /dev/md0: MBR Magic : aa55 Partition[0] : 4294967295 sectors at 1 (type ee) which presents me a partition with an ailing XFS filesystem on it. I'm hopeful that in my next round of an hour or two I can dig into superblock adventures. Thanks to all for all of the input! :-D -- David T-G See http://justpickone.org/davidtg/email/ See http://justpickone.org/davidtg/tofu.txt
