Ok, thank you, it's SAS SSD 15.3TB with 4osd/disk.
After reinstalled 1 disk, slow ops gone from that one so the others reported slow.
I think I need to reinstall all of them, very odd what happened :/

Look at the OSD logs, figure out which OSD.  Correlate with syslog / dmesg and smartctl etc.  SATA? If it’s all OSDs on the node likely the HBA.  If just one, likely the drive.
