[SOLVED] print_req_error: I/O error

[ARMITAGEIII]

hello ,i just bough a lsi 9210-8i in IT mode to expand the capacity of my motherboard ,and i started to have this strange errors in the syslog ,every disk passed smart long test before the array was build (i rebuilt it not long ago)

 

print_req_error: I/O error, dev sdl, sector 5860532992

 

can it be an HBA problem? the error was spoted ONLY in the drives attached to the HBA card ,the sata drives work flawless...

 

i think that everything points to the hba controller ,cause before this i had 2 sata card with 4 ports each and i never had any trouble...

 

all drives are mechanical ,no ssd / no cache either.

Those are likely harmless and possibly related to APM, IIRC one could get rid of them by changing the APM level, just don't remember if it was minimum or max that worked, change one of the disks to minimum and another to max:

 

hdparm -B 1 /dev/sdX

hdparm -B 254 /dev/sdX

See if it has any effect, note that settings will revert after a reboot.

Yep, and please report back if it works.

[ARMITAGEIII]

that parameter does disable or enable  apm ,where apm= disk noise/seek speed (AAM)  ,or that apm means spin up/spin down in unraid? just curious

It changes the power saving mode, on desktops hard drives usually there's not much difference, laptop drives will usually park heads sooner, or even go to sleep.

/dev/sdb:
 setting Advanced Power Management level to disabled
 APM_level      = off

....

/dev/sdm1:
 setting Advanced Power Management level to disabled
 APM_level      = off

 

done it was hdparm -B 255 /dev/sd* to apply to all my drives

ill check for a few days and report back
