SliMat Posted December 18, 2023 Share Posted December 18, 2023 Morning guys I needed to reboot my home UnRAID machine today and received a flurry of concerning alerts... Event: Unraid device dev2 SMART health [5] Subject: Warning [UNRAID] - reallocated sector ct is 177 Description: MB2000EAZNL_WMAY04119333_350014ee003203541 (dev2) Importance: warning Event: Unraid device dev2 SMART health [187] Subject: Warning [UNRAID] - reported uncorrect is 1020 Description: MB2000EAZNL_WMAY04119333_350014ee003203541 (dev2) Importance: warning Event: Unraid device dev2 SMART health [199] Subject: Warning [UNRAID] - udma crc error count is 13 Description: MB2000EAZNL_WMAY04119333_350014ee003203541 (dev2) Importance: warning Event: USB flash drive failure Subject: Alert [UNRAID] - USB drive is not read-write Description: ProductCode (sdc) Importance: alert I am guessing I have a rapidly failing dev2 as I had these 3 warnings by email in the order above? Also a failed USB key (?) - It has booted into UnRAID, which surprises me if the key has failed! I have checked on Connect and it shows the last backup as this morning when I shut the server down; I am assuming these are 2 completely separate faults and a replacement HDD and USB key will fix things? If I get a replacement USB key, am I better off copying the 'failed' one or restoring from Connect? Diags are attached. Thanks unraid-diagnostics-20231218-1023.zip Quote Link to comment
itimpi Posted December 18, 2023 Share Posted December 18, 2023 It looks like the device reporting issues is an Unassigned Device (/dev/sdi) rather than an array or pool device? There IS a message in the syslog about a failure to read a block from the flash drive but I wonder if that is a side-effect of the drive showing problems (particularly if that drive is connected via USB) rather than a genuine problem with the flash drive. You could try the process described here in the online documentation to rewrite the bz* type files - it will not do any harm and sometimes fixes being able to read marginal blocks from the flash drive.

SliMat Posted December 18, 2023 Author Share Posted December 18, 2023 Thanks @itimpi /dev/sdi is a SATA disk which I use purely for CCTV recordings, so it is not part of the array as it is a sacrificial drive which is permanently being written to... so, if its failing I'll just replace it. I was more concerned about the error showing on the Flash drive as I have never had a flash drive error. Ironically because of the age (10yrs +) of the USB disks I am using, I have just replaced the one in a rack server I have at a datacentre. The key in this machine is even older and does occasionally fail to boot and I have to reboot the server to get it to boot into UnRAID - so as a precaution I have ordered an 8Gb USB 2 key to be here tomorrow. I will try following the process mentioned above when I get a chance tomorrow just to see what the outcome is. Thanks again Quote Link to comment
