April 30, 20251 yr OK,so I got a little SMART error with Parity 1 (got 2...in case of failure). So I have had 0 problems with my server...until Unraid 7.0 was introduced. my diagnostic (fix common prob -app) says that: this message has been before also..... It appears that your server has a Marvel based hard drive controller installed within it. Some users with Marvel based controllers exhibit random drives dropping offline, recurring parity errors during checks etc. This tends to be exacberated if VT-D / IOMMU is enabled in the BIOS. Generally, LSI based controllers would be preferred over Marvel based controllers because of these issues. Note that these issues are out of Limetechs hands. Depending upon the exact combination of hardware present in your server, you may not have any problems whatsoever. If you have no problems, then this warning can be safely ignored, but future versions of Unraid (and later Kernel versions) may (or may not) present you with the previously mentioned issues. ok, so as I said...0 problems until now.....I am replacing my Parity and I have these short "piip" sounds during rebuild....and as looking to syslog there is a bunch of all kinds of color lines and so on as example: Apr 30 21:47:54 Tower kernel: sas: sas_ata_task_done: SAS error 0x89 Apr 30 21:47:54 Tower kernel: drivers/scsi/mvsas/mv_sas.c 1680:Release slot [518] tag[518], task [0000000036cf463e]: Apr 30 21:47:54 Tower kernel: drivers/scsi/mvsas/mv_94xx.c 656:command active 09004200, slot [518].

I can post a zip file about this if needed, but just to ask (as never before) this has happened..... What is this telling.....? How this will affect parity ? (now rebuilding) Other Disks ? Is data//parity (any part/integrity) to expected to be lost ? -and of course if someone would have a cure or explanation for this...I´m all ears...as I´m not very familiar with these kinds of problems.... I´m not (yet) panicking, but my main concern is of course the state on my server... I can post some capture of syslog if needed ? thanks so much ahead...
