October 19, 20214 yr Using 6.9.2 I bought a data disk about 3 months ago and added it to the array. Within the first 2 weeks I got a single read error. I checked some forum search results but didn't really get too much out of it. I decided to format the disk, change the SATA-connector (using a HBA, used another SATA out from the same reverse breakout cable) and rebuilt the disk. Afterwards the array turned good. Everything stayed fine for a couple of weeks. Recently the same disk failed the daily health check and showed 35 read errors. I ran an extended SMART check, but nothing suspicious. At least what I can make from it, according to google research. I was kinda busy the last couple of weeks but today I noticed the read errors jumped to 51. Is the disk failing? The concerned disk is disk9/sdi. Anything I could to try fix the disk or should I send it in? Edited October 20, 20214 yr by xaxos
October 20, 20214 yr It likely Seagate disk with LSI HBA, wakeup / power-save issue, most read error occur during disk wakeup.
October 20, 20214 yr Author Thank your very much, seems very likely that's exactly my problem. Will update this post after rebuilding the disk.
