Nexius2 Posted February 26, 2021 Share Posted February 26, 2021 Hello, I'm new to unraid and started my server in september or something like that. I've been adding disk as I was migrating my data. since december I would say I'm having some issues with parity sync. every time I have a parity sync (manual or scheduled) I loose some disks. it just says it's got errors and removes it from the array. but when I test the drive, it is fine. I've been changing disks, rebuilding arrays, adding/removing disks, I've tryed all I could think off but I still have the issue. could someone help? nostromo-diagnostics-20210226-1443.zip Quote Link to comment
Squid Posted February 26, 2021 Share Posted February 26, 2021 Have you tried reseating the cabling to the drives and to the HBA? Quote Link to comment
Nexius2 Posted February 26, 2021 Author Share Posted February 26, 2021 (edited) I've got a Dell H200 6 Gbit/S SAS LSI 9210-8i connected to a Lenovo 16-Port 6 Gbit/s SAS-2 Sata Expander connected to the backplane. all cables seem ok, and everything works well when I have no parity disk. (I meen it does not disable other disks). I have reduced my number of drives because I was suggested a power issue but it does not resolve the problem (removed 8 drives) I only had 8To seagate errors until now and todays try made 2 WD fail also. I stopped the parity sync, stopped the array, restarted the array and disks are connected again so I realy don't think of a power or cable issue.

Vr2Io Posted February 26, 2021 Share Posted February 26, 2021 I use Lenovo expander with different HBA without issue, you need stress test or change / replace hardware to rule out the problem. [7:0:16:0] enclosu LENOVO SAS CARD 013a - /dev/sg20 Quote Link to comment
