[Bug 239801] mfi errors causing zfs checksum errors
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=239801 --- Comment #9 from Daniel Mafua --- I think I can safely say that switching to the mrsas driver has resolved my problem. Thanks to everyone! For reference I was experiencing problems with Dell servers of various models using the PERC H330 controller. Firmware versions were 25.3.0.0016 and 25.5.2.0001. A PERC H310 Adapter Firmware: 20.13.0-0007 wasn't experiencing the problem and continued to use the mfi driver. -- You are receiving this mail because: You are the assignee for the bug. ___ freebsd-bugs@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-bugs To unsubscribe, send any mail to "freebsd-bugs-unsubscr...@freebsd.org"

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=239801 --- Comment #8 from Timur I. Bakeyev --- (In reply to Andriy Gapon from comment #7) Yes. Basically, it has a correct statement - for PERC H730P mrsas driver is a better(and proper) option. I.e. mfi shouldn't even be picked up by the kernel by default for it. After switching to mrsas we've seen double in performance and overall bandwidth, not to mention disappearing of those weird I/O error bugs. -- You are receiving this mail because: You are the assignee for the bug. ___ freebsd-bugs@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-bugs To unsubscribe, send any mail to "freebsd-bugs-unsubscr...@freebsd.org"

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=239801 Hiroki Sato changed: What|Removed |Added Status|Open|In Progress --- Comment #5 from Hiroki Sato --- (In reply to Daniel Mafua from comment #4) Thanks for your report. I have several other systems which are suffering from the same problem. Here is information about this problem which I got so far: * mfi(4) can report I/O errors which is not related to an actual hardware failure after upgrading FreeBSD to 11.3 or 12.0. * The error does not depend on ZFS while ZFS is very likely to report checksum errors of the zpool. On a system using UFS, the I/O error can cause a system panic, boot failure, or something fatal. * It seems that the I/O error depends on a specific firmware version. Some older firmware versions work fine even with mfi(4) on 11.3 and 12.0. * If the device is also supported by mrsas(4), switching to it will solves the error. Note that it will cause an incompatibility issue---mfi(4) uses /dev/mfi* device nodes for the attached drives and mfiutil(8) as the userland utility. mrsas(4) uses /dev/da* and a vendor-supplied utility such as megaCli instead. I am investigating what caused this regression but a workaround is to use mrsas(4) instead of mfi(4) by specifying hw.mfi.mrsas_enable="1" at boot time. -- You are receiving this mail because: You are the assignee for the bug. ___ freebsd-bugs@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-bugs To unsubscribe, send any mail to "freebsd-bugs-unsubscr...@freebsd.org"

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=239801 --- Comment #4 from Daniel Mafua --- The firmware has not been upgraded on any of the servers. I was able to switch from mfi to mrsas on one of the servers, but because they're at remote locations I need to be careful on how aggressive I am on this. I've successfully scrubbed out errors and everything is clear now. However, this also has been the case after any reboot, and errors started appearing again around 3-4 days later. It will probably take me two weeks to verify it's working okay, then I'll report back. -- You are receiving this mail because: You are the assignee for the bug. ___ freebsd-bugs@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-bugs To unsubscribe, send any mail to "freebsd-bugs-unsubscr...@freebsd.org"
[Bug 239801] mfi errors causing zfs checksum errors
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=239801 --- Comment #3 from ma...@tols.org --- Hi, so my bit more detailed story is this: We have 2 identical Dell R730xd systems with each 12 6TB drives in them, running on raidz2. It also has 2 SSD's in it which add to the system as ZIL and cache drives. Both have been running 11.1-RELEASE which gave no problems. The systems also have been on 11.2-RELEASE, also without any problems. In between the upgrades I have also done "zpool upgrade" where available. Then I upgraded to version 11.3-RELEASE, and trusting that all was as flawless as in the first 2 years, I gave it not much attention other then keeping an eye on it from the monitoring host. Unfortunately we only monitor zpool status, which has been ONLINE throughout the entire process. I left it running for quite a while when at some point I wanted to show the pool to someone and found out both systems had a few 100K checksum errors on each of the 12 drives in the pool. Not on the SSDs that make up the ZIL and cache. One of the systems was running 11.3-RELEASE-p1, and the other was running 11.3-RELEASE-p3. My path to fixing this was this: - Google for the issue, and find out mrsas was a potential fix - Change the system on p3 to mrsas and reboot - Do a zpool scrub to autoheal all broken sectors, which ended up fixing almost 100GB of data - Do a zpool clear to clear the counters - Do another zpool scrub to see if the counters remain 0, which they did. - Do the same on the other system, which was on p1, and bring it to p3 in the process Hope this helps, Marco van Tol -- You are receiving this mail because: You are the assignee for the bug. ___ freebsd-bugs@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-bugs To unsubscribe, send any mail to "freebsd-bugs-unsubscr...@freebsd.org"

I could fix this by changing the controller driver from mfi to mrsas. See https://www.freebsd.org/cgi/man.cgi?query=mrsas=0=0=FreeBSD+11.3-RELEASE=default=html on details on how to do that. (loader.conf variable) Please make sure you do a "zfs scrub" afterwards to autoheal all checksum errors.

[Bug 239801] mfi errors causing zfs checksum errors
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=239801 Bug ID: 239801 Summary: mfi errors causing zfs checksum errors Product: Base System Version: 11.3-RELEASE Hardware: amd64 OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: b...@freebsd.org Reporter: ma...@dempseyuniform.com After upgrading to FreeBSD 11.3 I began having storage issues. (I may have experienced the same problem when testing FreeBSD 12.0). At first I thought it was a problem with upgrading my ZFS pool to include the update for spacemap_v2, but now I think it's a lower level problem. After a day or two, I start to see checksum errors appear on a pool. Doing a scrub on the pool just results in more errors. If I restart the machine, I can then scrub the pool and errors no longer appear, then after a few days it happens again. There's only one or two machines I haven't upgraded my zpool on, but I think it's just a coincidence that I saw the problem after upgrading the zpool (thinking the upgrade went okay). But I haven't experienced problems on the one machine I haven't upgraded the pool on. All (3) servers are Dell PowerEdge servers, using a PERC raid controller configured as JBOD. They have two drives configured as a zfs mirror. One machine had a drive failure a few months ago, which was replaced and running fine, but otherwise all machines have been running for years with no issues and never failed a scrub until the upgrade. They're at different locations, so that probably rules out power issues. mfi0 Adapter: Product Name: PERC H330 Adapter Serial Number: 59N01F6 Firmware: 25.3.0.0016 RAID Levels: JBOD, RAID0, RAID1, RAID5, RAID10, RAID50 Battery Backup: not present NVRAM: 32K Onboard Memory: 0M Minimum Stripe: 64K Maximum Stripe: 64K mfi0 Physical Drives: 0 ( 932G) JBOD SCSI-6 S0 1 ( 932G) JBOD SCSI-6 S1 Errors Reported in /var/log/messages kernel: mfi0: I/O error, cmd=0xfef9a4a8, status=0x3c, scsi_status=0 kernel: mfi0: sense error 0, sense_key 0, asc 0, ascq 0 kernel: mfisyspd1: hard error cmd=write 675298440-675298991 kernel: mfi0: I/O error, cmd=0xfef99dc0, status=0x3c, scsi_status=0 kernel: mfi0: sense error 0, sense_key 0, asc 0, ascq 0 kernel: mfisyspd1: hard error cmd=write 675298504-675299015 kernel: mfi0: I/O error, cmd=0xfef9c048, status=0x3c, scsi_status=0 kernel: mfi0: sense error 0, sense_key 0, asc 0, ascq 0 kernel: mfisyspd0: hard error cmd=write 675298504-675299015 kernel: mfi0: I/O error, cmd=0xfef9ae38, status=0x3c, scsi_status=0 kernel: mfi0: sense error 0, sense_key 0, asc 0, ascq 0 kernel: mfisyspd0: hard error cmd=write 675298440-675298991 kernel: mfi0: I/O error, cmd=0xfef9c048, status=0x3c, scsi_status=0 kernel: mfi0: sense error 0, sense_key 0, asc 0, ascq 0 kernel: mfisyspd0: hard error cmd=write 675298440-675298991 kernel: mfi0: I/O error, cmd=0xfef9afd0, status=0x3c, scsi_status=0 kernel: mfi0: sense error 0, sense_key 0, asc 0, ascq 0 kernel: mfisyspd1: hard error cmd=write 675298440-675298991 kernel: mfi0: I/O error, cmd=0xfef98bb0, status=0x3c, scsi_status=0 kernel: mfi0: sense error 47, sense_key 15, asc 175, ascq 175 kernel: mfisyspd1: hard error cmd=write 675298440-675298991 kernel: mfi0: I/O error, cmd=0xfef9a6c8, status=0x3c, scsi_status=0 kernel: mfi0: sense error 0, sense_key 0, asc 0, ascq 0 kernel: mfisyspd0: hard error cmd=write 675298440-675298991 kernel: mfi0: I/O error, cmd=0xfef9b0e0, status=0x3c, scsi_status=0 kernel: mfi0: sense error 0, sense_key 0, asc 0, ascq 0 kernel: mfisyspd0: hard error cmd=write 675298440-675298991 -- You are receiving this mail because: You are the assignee for the bug. ___ freebsd-bugs@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-bugs To unsubscribe, send any mail to "freebsd-bugs-unsubscr...@freebsd.org"
