Hi Konstantin, I dropped the SATA SSDs from /sys/block and rescanned it. Re-running `ceph-bluestore-tool fsck` resulted in the same output (unexpected aio error). Syslog says the drive is not in write-protect mode, however smart says life remaining is at 1%. Drives have approximately 42k power-on hours. $ lsscsi -g [0:0:0:0] disk ATA ST1000NX0423 TN04 /dev/sda /dev/sg0 [1:0:0:0] disk ATA ST1000NX0423 TN04 /dev/sdb /dev/sg1 [2:0:0:0] disk ATA Micron_5200_MTFD U004 /dev/sdc /dev/sg2 [3:0:0:0] disk ATA Micron_5200_MTFD U004 /dev/sdd /dev/sg3 [4:0:0:0] disk ATA Micron_5200_MTFD U004 /dev/sde /dev/sg4 [5:0:0:0] disk ATA Micron_5200_MTFD U004 /dev/sdf /dev/sg5 [6:0:0:0] disk ATA Micron_5200_MTFD U004 /dev/sdg /dev/sg6 [7:0:0:0] disk ATA Micron_5200_MTFD U004 /dev/sdh /dev/sg7 $ echo 1 > /sys/class/scsi_generic/sg3/device/delete $ tail -n 10 /var/log/messages Jul 31 07:08:03 ceph-osd4 rsyslogd: -- MARK -- Jul 31 07:28:03 ceph-osd4 rsyslogd: -- MARK -- Jul 31 07:48:03 ceph-osd4 rsyslogd: -- MARK -- Jul 31 08:08:03 ceph-osd4 rsyslogd: -- MARK -- Jul 31 08:28:03 ceph-osd4 rsyslogd: -- MARK -- Jul 31 08:48:03 ceph-osd4 rsyslogd: -- MARK -- Jul 31 08:51:41 ceph-osd4 kernel: [144240.695000] sd 3:0:0:0: [sdd] Synchronizing SCSI cache Jul 31 08:51:41 ceph-osd4 kernel: [144240.695063] sd 3:0:0:0: [sdd] Stopping disk Jul 31 08:51:41 ceph-osd4 kernel: [144241.011641] ata4.00: disabled $ echo "- - -" > /sys/class/scsi_host/host3/scan $ tail -n 10 /var/log/messages Jul 31 08:52:48 ceph-osd4 kernel: [144308.293457] ata4.00: Enabling discard_zeroes_data Jul 31 08:52:48 ceph-osd4 kernel: [144308.293480] sd 3:0:0:0: [sdi] 3750748848 512-byte logical blocks: (1.92 TB/1.75 TiB) Jul 31 08:52:48 ceph-osd4 kernel: [144308.293481] sd 3:0:0:0: [sdi] 4096-byte physical blocks Jul 31 08:52:48 ceph-osd4 kernel: [144308.293486] sd 3:0:0:0: [sdi] Write Protect is off Jul 31 08:52:48 ceph-osd4 kernel: [144308.293493] sd 3:0:0:0: [sdi] Write cache: enabled, read cache: enabled, doesn't support DPO or FUA Jul 31 08:52:48 ceph-osd4 kernel: [144308.293517] sd 3:0:0:0: Attached scsi generic sg3 type 0 Jul 31 08:52:48 ceph-osd4 kernel: [144308.293670] ata4.00: Enabling discard_zeroes_data Jul 31 08:52:48 ceph-osd4 kernel: [144308.297332] sdi: sdi1 Jul 31 08:52:48 ceph-osd4 kernel: [144308.297898] ata4.00: Enabling discard_zeroes_data Jul 31 08:52:48 ceph-osd4 kernel: [144308.297928] sd 3:0:0:0: [sdi] Attached SCSI removable disk $ lsscsi -g [0:0:0:0] disk ATA ST1000NX0423 TN04 /dev/sda /dev/sg0 [1:0:0:0] disk ATA ST1000NX0423 TN04 /dev/sdb /dev/sg1 [2:0:0:0] disk ATA Micron_5200_MTFD U004 /dev/sdc /dev/sg2 [3:0:0:0] disk ATA Micron_5200_MTFD U004 /dev/sdi /dev/sg3 [4:0:0:0] disk ATA Micron_5200_MTFD U004 /dev/sde /dev/sg4 [5:0:0:0] disk ATA Micron_5200_MTFD U004 /dev/sdf /dev/sg5 [6:0:0:0] disk ATA Micron_5200_MTFD U004 /dev/sdg /dev/sg6 [7:0:0:0] disk ATA Micron_5200_MTFD U004 /dev/sdh /dev/sg7 _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
