MikaelTarquin Posted August 1, 2021 Posted August 1, 2021 I just now got a Warning message from my server that my array has errors. However, it only lists it as a warning, and I just ran a SMART test on that drive and got "Completed without error." I'm not sure what, if anything, I should do about this. I sure would hate to have to replace such a new (and expensive!) drive.

JorgeB Posted August 1, 2021 Posted August 1, 2021 It's logged as a disk problem, but in LBA 0 which is strange, still should run an extended SMART test, if the test passes swap cables/slot with another disk to rule that out. Quote
MikaelTarquin Posted August 1, 2021 Author Posted August 1, 2021 Ok, I'm running an extended test now. Quote
MikaelTarquin Posted August 2, 2021 Author Posted August 2, 2021 (edited) The extended test just finished and looks like there's definitely a problem.

MikaelTarquin Posted August 2, 2021 Author Posted August 2, 2021 I'm going to try RMAing the drive. With 2 parity drives, am I okay to just stop the array, pull the drive out, and start the array again with that drive in emulated mode until the replacement is here? Quote
trurl Posted August 2, 2021 Posted August 2, 2021 Any access of disk15 will require reading all other disks to emulate. Quote
MikaelTarquin Posted August 2, 2021 Author Posted August 2, 2021 What would be the best practice, then? Quote
trurl Posted August 3, 2021 Posted August 3, 2021 Should be fine but some performance impact from emulation. Quote
