October 3, 20223 yr Hi. i have my system upp and running for about 5 years. have had a few parity errors. but this time i got 900K+ it may have bean an unclean shutdown. daughter got a hold of the power button. Did one more paritycheck but still alot of errors. cant fins anything wrong with the drives and should have Write corrections to parity disk on.
October 3, 20223 yr Community Expert 900K is a lot for an unclean shutdown, there weren't any other recent changes?

You don't want to corrupt parity because of problems with another disk, or bad RAM, or whatever. Each of those parity checks corrected different sectors. Bad RAM is a very likely suspect.

You shouldn't even attempt to run any computer unless RAM is working perfectly. Everything goes through RAM, your data, the OS and other executable code, everything. The cpu can't do anything with anything until it is loaded into RAM.
October 3, 20223 yr Author Thanks. will preform memtest. nothingesle that i can think of. haven changed any harware for the last year.

So memtest show no errors after one pass. any other suggestions?
October 4, 20223 yr Community Expert Run another check, if no more errors are found you are likely fine.

October 4, 20223 yr Community Expert Diagnostics taken without rebooting after each parity check are needed to compare each run. If there are obvious I/O errors that would also be apparent in diagnostics. If the only thing happening is actual sync errors, no way to determine what disk since parity is just a single bit and can only tell you that it doesn't match all the other disks combined.

New day new parity check. 497622 errors. attached is diagnostics. vildkatt-diagnostics-20221006-0750.zip

October 7, 20223 yr Author Did one correcting and one non correcting. 900k for the first one and 0 for the second one. Is that acceptable pr should i make one more?
October 8, 20223 yr Community Expert That's good for now, of course we still don't know what caused the initial problem, use the server normally for a week or two and then run another check.
