May 30, 20242 yr I am trying to replace two drives in the array. sdm is the parity drive. sdi and sdj are the new drives replacing two others that i have already taken out. when i go to array operation i get a message stating disk in parity slow is not biggest. but the disk is exact same disk as the two new ones. they were spares. i have already cleared the drives. do i need to format the drive before adding it to the array?
May 30, 20242 yr Community Expert Make sure any existing partitions are removed. if that does not work then I suggest posting your systems’ diagnostic zip file with the drives installed.
May 30, 20242 yr Author hive-diagnostics-20240530-1242.zip Are you suggesting to remove any existing partitions from the new drives? I did clear the drives from unassigned devices. Attached is the diagnostics file.
May 30, 20242 yr Community Expert If you look in the syslog you will see that it reports the parity drive as May 30 12:24:30 Hive kernel: mdcmd (1): import 0 sdm 2048 15625878508 0 ST16000VE000-2L2103_ZL20S6BC and later disk7 as May 30 12:24:30 Hive kernel: mdcmd (8): import 7 sdi 64 15625879500 0 ST16000VE000-2L2103_ZL20DAN8 so that the parity drive is not the largest in terms of sectors available for use. Normally Unraid starts HDD device partition 1 at sector 64 and SSD partition 1 at sector 64. That was why I suggested removing any existing partitions as it looks as if the parity drive already has partition 1 set to start at sector 2048 rather than 64. No
May 30, 20242 yr Author ah. makes sense. what would be the recommended solution? replace the parity drive first with one of the newer ones and then replace the drives?
May 30, 20242 yr Community Expert You can unassign parity, start array, stop array, erase the current parity partition, then reassign it and Unraid will create a new partition starting on sector 64, you can then upgrade the other disk.
May 30, 20242 yr Author alright, i kind of figured that was the case. now we wait for it to rebuild, sigh.... thank you. Edited May 30, 20242 yr by exdox77
June 2, 20242 yr Author @JorgeB quick question. i started the array back up the other day and it started the parity sync just fine. everything was working up until yesterday when everything went offline and i wasnt even able to SSH into the server or access the webui. the array seem to be offline as well, but I see disk activity. I will pull the diagnostics in a bit and upload them. But wanted to get this out here to see if you knew something off the top.
June 2, 20242 yr Author nevermind, during this whole process the usb drive got corrupt!!! replaced and now doing the sync again.
