https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=248727 Louis Bertrand <louis@bertrandtech.ca> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |louis@bertrandtech.ca --- Comment #7 from Louis Bertrand <louis@bertrandtech.ca> --- On a Dell R630 PERC H330 Mini with zfs raidz level 1 and 14.1 stable, I was getting multiple read errors (several thousand in a few minutes). There was no loss of data, but definitely loss of confidence! Replacing mfi(4) with mrsas(4) solved the problem. Sorry, I wasn't thinking of reporting a bug while dealing with the emergency so I didn't record error messages. device 0 is a pair of hardware mirrored drives as root 6 disks in "Non RAID" (according to the BIOS config utility) pooled into raidz. I tried the hw.mfi.mrsas_enable="1" line in device.hints but the kernel kept loading mfi regardless. Finally I made a new kernel and commented out device mfi. After dealing with the renaming of disks, the system seems stable. Humble suggestion: It seems that mfi is for legacy devices and the preferred module is mrsas. Can mrsas be given priority by default? -- You are receiving this mail because: You are the assignee for the bug.help
