October 9, 20205 yr Community Expert 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. mercedes-diagnostics-20201009-1015.zip
October 9, 20205 yr Community Expert 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.

October 9, 20205 yr Author Community Expert 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
October 9, 20205 yr Community Expert 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.
