Hello,

 

since a few days i have the following error in my syslog:

 

Oct 30 13:53:35 Avalon kernel: blk_update_request: critical target error, dev sdd, sector 486672334 op 0x3:(DISCARD) flags 0x800 phys_seg 1 prio class 0
Oct 30 13:53:35 Avalon kernel: BTRFS warning (device sdd1): failed to trim 1 device(s), last error -121

 

A manual use of

 

fstrim -v /mnt/cache/ (/mnt/cache/=sdd1)

 

and the use of the Trim-Plugin generates this error. In my Opinion this is a new error, never had this error before. The SSD is connected to a HBA with IT-Mode flashed, the Firmware is 19. But i have never had this error before so i think is it not ascribe to the HBA Firmware.

 

How can i check and repair this an the blk_update_request: critical target error?

 

Thanks a lot

Christian

 

Not all firmware versions on HBA's support trim.  ie: on my controllers, the latest is v20, but only v16 supports trim.  Does the command succeed if you connect the SSD to the motherboard?

Hi,

now i have tested the SSD on a SATA-Port at the mainboard, and voila no error:

 

root@Avalon:~# fstrim -v /mnt/cache/
/mnt/cache/: 232.9 GiB (250048569344 bytes) trimmed

 

For me means that

 

a) downgrade the firmware of the HBA from 19 to 16

or

b) buy a respectively two SATA III PCIe Cards because the Mainboard of my HP Proliant hat only SATA II onboard.
