https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=241476 Bug ID: 241476 Summary: zfs checksum errors with FreeBSD 11.3 and mps driver Product: Base System Version: 11.3-RELEASE Hardware: amd64 OS: Any Status: New Severity: Affects Some People Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: spam+bugs.freebsd.org@dentarg.net Created attachment 208573 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=208573&action=edit Output from "mpsutil show all" We have two servers, Jon and Samwell. The servers are SuperMicro SuperStorage Server 2027R-E1R24L with the X9DR7-LN4F motherboard, 2x Xeon E5-2620v2 and 256GB ECC RAM. The motherboard has the LSI SAS 2308 controller. Both servers have 22x 960GB Samsung SSD (SV843, SM843T, SM863, SM863a). Each server has a zpool ("db") with 11 mirrors consisting of the SSDs. They boot of another zpool. The servers are using the mps driver. The servers are configured to scrub regularly: $ cat /etc/periodic.conf daily_scrub_zfs_enable="YES" daily_scrub_zfs_default_threshold="7" # days between scrubs daily_status_zfs_enable="YES" We upgraded both servers from FreeBSD 11.2 to 11.3 at 2019-09-04. Every 10th minute a cronjob checks that the pools are healthy, if not, we get an alert. After going to FreeBSD 11.3, both servers have alerted twice: 2019-09-20 04:10 Jon 2019-10-12 08:20 Jon 2019-10-09 05:10 Samwell 2019-10-24 04:10 Samwell about the error https://illumos.org/msg/ZFS-8000-8A (see attached files for details; outputs from zpool status) So far we have only seen errors reported for what I understand is metadata, example: errors: Permanent errors have been detected in the following files: <0x16dc>:<0x498> Issuing another "zpool scrub" makes zpool status say "errors: No known data errors" and then a "zpool clear" clears the checksum error counts. We see no errors in /var/log/messages. Only "ZFS: vdev state changed" rows when a scrub starts. I've seen and read bug #239801, but opted to open a new bug as we are using a different driver. -- You are receiving this mail because: You are the assignee for the bug.help
