August 6, 20241 yr Hi, around a week ago the parity drive was disabled, so I took another one and started to rebuild it. It finished without any problems in 11 hours. Today I got a notification about a disk disabled in the array and the parity disk that I changed was disabled. I don’t have any idea for what is the problem config: HBA: Dell PERC H310 SAS (FW 20.00.00IR) Drive: ST6000NM34 SAS (Precleared and verified without error) Cable: SAS SFF-8087 to 4x SFF-8482 Molex PSU: Cooler Master MWE-V2 White 650W mv-diagnostics-20240806-1411.zip
August 6, 20241 yr Community Expert Diags are after rebooting, so we can't see what happened, re-sync parity and post new diags before rebooting if it happens again
August 8, 20241 yr Author Yesterday the Parity reconstructed without error, today I boot up the server and same problem. mv-diagnostics-20240808-1432.zip
August 8, 20241 yr Community Expert Looks more like a power/connection issue, replace both cables, or swap them with a different disk and re-sync parity
August 8, 20241 yr Author I have already swapped the cable, if it is not the disk the problem is on the psu, the SAS HBA or the cable. But of the three I don’t know where is the problem
August 8, 20241 yr Community Expert It can still be the disk, but doesn't look like, try swapping whatever is easier for you.
August 25, 20241 yr Author Nothing, I swapped cable, disks and ports and now it seem like a disk is starting and stopping. At this point I’m pretty sure that is a psu issue but for an array of 7 disk I don’t know how much big need to be a psu. I have a 650w and in a parity rebuild is using about 200w from the wall and with a vm I have never seen over 300w. For me it is really strange
August 26, 20241 yr Community Expert A good 500W PSU is enough for that, make sure your are not using excessive number of splitters.
August 26, 20241 yr Author I have 4 disk SATA connected directly to the psu cable but only 2 disk on a 4 SATA PW cable to split up the load. The other 3 disk are connected via Molex because are SAS. I tried power those SAS with SATA PW and Molex. Now to split up 3 SATA on one cable, one SATA and one SAS on another and the last two SAS on molex. Still problem, now on the two disks: the SATA and SAS one in one cable. I don’t know how to do to fix it
August 26, 20241 yr Community Expert Solution Could also be a bad PSU, if you have a different one try swapping it
August 26, 20241 yr Author At this point I’m thinking the same, I will mark the post as a solution for anyone in the future who possibly needs it but because I don’t have another pay on hand I will update this post when I have a new psu. Thank for the help
