"blk_update_request: critical target error, dev sda, sector number op0x9 : (write_zeroes) flags 0x800 phys_seg 0 prio class 0" 

the server work fine and i do not see problems

what can be the reason  ?

Hi @mosheshiper,

In researching the error, it seems like a critical error related to your storage device (dev sda) indicating a write problem to a specific sector.

Troubleshooting suggestions include:

• Check the disk health: smartctl -a /dev/sda
• Run a file system check: fsck /dev/sda
• Check for bad sectors on the disk: badblocks -v /dev/sda

You might want to run a backup. I suggest contacting your IT team for assistance.

I will talk with my storage guy
