In a data server, we have a RAID array of 5 disks joined in an XFS filesystem. The dmesg output is:

IPv6: ADDRCONF(NETDEV_CHANGE): enp134s0f0: link becomes ready
XFS (sda2): Mounting V5 Filesystem
XFS (sda2): failed to locate log tail
XFS (sda2): log mount/recovery failed: error -74
XFS (sda2): log mount failed

clocksource: timekeeping watchdog on CPU0: hpet retried 2 times before success
usb 1-2.5: USB disconnect, device number 5

and the output of xfs_repair /dev/sda2 is:

bad hash table for directory inode 66571995395 (no data entry): rebuilding

I will appreciate any help or hint.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
