Hello All, I am struggling to recover my system after a PSU failure. One of the hard drives throws some read errors, and that happen to be my root drive... My system is CentOS 7, and the root partition is a part of LVM. [root@mgmt ~]# lvscan ACTIVE '/dev/centos/root' [<98.83 GiB] inherit ACTIVE '/dev/centos/home' [<638.31 GiB] inherit ACTIVE '/dev/centos/swap' [<7.52 GiB] inherit [root@mgmt ~]# [root@tftp ~]# file -s /dev/centos/root /dev/centos/root: symbolic link to `../dm-3' [root@tftp ~]# file -s /dev/centos/home /dev/centos/home: symbolic link to `../dm-4' [root@tftp ~]# file -s /dev/dm-3 /dev/dm-3: SGI XFS filesystem data (blksz 4096, inosz 256, v2 dirs) [root@tftp ~]# file -s /dev/dm-4 /dev/dm-4: SGI XFS filesystem data (blksz 4096, inosz 256, v2 dirs) [root@tftp ~]# xfs_repair /dev/centos/root Phase 1 - find and verify superblock... superblock read failed, offset 53057945600, size 131072, ag 2, rval -1 fatal error -- Input/output error [root@tftp ~]# smartctl shows some pending sectors on /dev/sda, and no reallocated sectors (yet?). Can someone please give me a hand to bring root partition back to life (ideally)? Or, at least, recover a couple of critical configuration files... --- Best regards, Andrey
