Previously I won't have any parity check sync errors for months. But lately, after I replaced 1 x HDD (faulty) and 1 x 8087 cable (replaced cable due to UDMA CRC error count). Sync errors have been popping up. Is that a cause for concern ?
For example, I did a parity check on :
24-Jan-2022, there were 766 sync errors
31-Jan-2022, there were 272 sync errors
01-Feb-2022, there were 128 sync errors
I'm in the progress of my 4th parity checks, and there are still 128 sync errors
Can experts please kindly advise on what I should do ?
Attached is the diagnostics ZIP for your reference.
By the way, in the event that I need to replace a current HDD (8/10TB) with a higher capacity HDD (14TB), what's the correct procedure ?
Is it use new 14TB HDD to replace either 1 of the parity HDD, then use the replaced parity HDD as normal data HDD
