dpc2 Posted June 27, 2019 Share Posted June 27, 2019 I've been having issues for the last week where I get an error that 5 disks have read errors. I reboot and all is well. Today I got that message plus my Disc 2 has been disabled. This may be a cabling or SASLP problem, but I haven't touched anything or rebooted. What's the best way to proceed from here? Diagnostics attached below. Running 6.7.2 tower-diagnostics-20190627-2100.zip Thank you! Quote Link to comment
JorgeB Posted June 28, 2019 Share Posted June 28, 2019 1-replace the SASLP with an LSI 2-rebuild disabled disk (assuming SMART is OK, it's not on the diags because that disk and several others on the SASLP dropped offline) Quote Link to comment
dpc2 Posted July 1, 2019 Author Share Posted July 1, 2019 I've ordered an LSI and will install it next week. In the meantime, I hadn't powered down the server and my monthly parity check (with corrections on) kicked off overnight. I stopped the check at the 8 hour mark, powered down, checked all cables, and powered up again. Now running an extended SMART test on the disabled drive. My question is, should I try to rebuild the disabled disc, or should I try to re-enable it as is and then check parity? I'm afraid that my parity is no longer valid since it ran with a disc disabled (and had millions of errors). On the other hand, data on the disabled disk may have errors because it was disabled due to a write error. I wonder which path is the lesser of two evils. Seems like I could lose a bit of data either way. Quote Link to comment
Frank1940 Posted July 1, 2019 Share Posted July 1, 2019 IF it were me, I would be waiting until that new card appeared. Then start with the disk that has disabled and look at the files that are on it. Determine which one are irreplaceable. Than copy them off in lots to another place. If the file copies, it is probably good. If this is too much effort, you could look at the creation and only check the most recent ones. The reason for doing it this way is that you have two chances of for recovery. If that data is trashed, you can then try a rebuild! Quote Link to comment

Thank you, Johnnie. Running the rebuild now and am confident that all will be good. Will also change out the controller. Quote Link to comment
