https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D243683 Bug ID: 243683 Summary: Need to add quirk for Micron 5300 series of ssd drives Product: Base System Version: 12.1-STABLE Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: satan@Ukr.net Created attachment 211142 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=3D211142&action= =3Dedit Adding quirk to disable UNMAP/TRIM for Micron 5300 SSD Quirks for a Micron 5300 pro sata ssd drive. When truing to use it in zfs pool find terrible performance caused by zfs sending trim command to ssd. For example samsung PM863a worked in same pool have x 10 better performance. After disable trim via quirks for micron get= =20 performance near or beatter then PM863a. So looks like Micron have troble w= ith=20 trim/unmap on that type of devices. In attachment I place quick patch adding quirks to scsi_da.c and ata_da.c=20 where simply adding quirk for 4k (looks like no needed ) and DA_Q_NO_UNMAP/ADA_Q_NO_TRIM for that's device's. quirks tested on 12.1-STABLE and 11.2-STABLE=20=20 On 11.2 only for for scsi_da.c as quirk ADA_Q_NO_TRIM doesn't exist. Its will be good if some body can confirm that fix is right and push change= s to upstream=20 Patch again 12.1-STABLE FreeBSD 12.1-STABLE r357144 --=20 You are receiving this mail because: You are the assignee for the bug.=
