unmesh Posted May 23, 2023 Share #1 Posted May 23, 2023 I have DSM 6.2.3 U3 running on Jun's bootloader on ESXi 7.0 U3 with hard drives passed through using RDM. One of them reported as crashed earlier today. Fortunately, I have a backup but would like to get this server up and running again. I tried deleting the storage pool in DSM and re-adding it but it still shows crashed. I looked at the drive using ESXI SMART and got this: Parameter Value Threshold Worst Raw --------------------------------- ----- --------- ----- --- Health Status OK N/A N/A N/A Write Error Count 0 0 N/A 0 Read Error Count 251 51 N/A 251 Power-on Hours 34 0 34 130 Power Cycle Count 52 0 N/A 52 Reallocated Sector Count 0 140 N/A 0 Drive Temperature 32 0 N/A 32 Sector Reallocation Event Count 0 0 N/A 0 Pending Sector Reallocation Count 2 0 N/A 2 Uncorrectable Sector Count 0 0 N/A 0 Does the combination of the read error count and the pending sector reallocation count explain why DSM cannot use this hard drive? Anything else to try before I get and install a new hard drive? Quote Link to comment Share on other sites More sharing options...
unmesh Posted May 25, 2023 Author Share #2 Posted May 25, 2023 I just got a new hard drive and copied all the files over from another NAS that serves as a nearline backup Quote Link to comment Share on other sites More sharing options...
