rtinker Posted February 19, 2021 Share Posted February 19, 2021 Hello. Getting errors on my parity disk, so I want to replace it. I will get a larger disk (6GB --> 8GB) but I do not have any additional disk interface connections, so it has to be a swap. Is it just stop the array, swap it, and restart the array? Also, and this is terrible - but I am not sure I know which drive (physically) is the parity - I saw a disk identify somewhere but is there one for the Parity too? Thanks. Quote Link to comment
Tom3 Posted February 19, 2021 Share Posted February 19, 2021 (edited) You may find it helpful to read on the Wiki about Parity drives: https://wiki.unraid.net/UnRAID_6/Storage_Management#Parity_Disks One possibility for identifying disks may be to spin down all the disks, then spin them up one at a time while looking at each disk activity indicator LED. -- Tom Edited February 19, 2021 by Tom3 fix typo Quote Link to comment
rtinker Posted February 19, 2021 Author Share Posted February 19, 2021 Thanks Tom - confirmed the process to replace it and yes, that sounds like a viable approach to finding the party drive as at most, I would have two drives spinning at a time. Quote Link to comment
itimpi Posted February 19, 2021 Share Posted February 19, 2021 Also make sure you note down the serial number of the old parity drive (displayed in the unRaid GUI) so you can check you are removing the correct drive. Quote Link to comment

S80_UK Posted February 19, 2021 Share Posted February 19, 2021 I always keep a print out (or a saved PDF) of the web UI Main page with all drives listed as a handy reference. I also recommend the "disklocation" plugin. It takes a few minutes to assign the drives to specific locations, but once done it's a great help when it comes to future maintenance. 1 1 Quote Link to comment
PeteAron Posted February 20, 2021 Share Posted February 20, 2021 Unraid identifies each disk by the last four digits of its serial number, for example JA1Z. The serial number s/n is written on the label of every disk. When i add a disk to my array, i write the four letter "name" on a small piece of tape and tape that to the rear of the drive, so i can identify them easily. I have a 4U rackmount case, with 3 5-drive cages. on the frame containing each bay, i put labels in order from top to bottom in the cage with each drive's name. That way, it is easy for me to find the right cage and the right drive just by looking at my array in the web interface. If you put a couple of minutes into labelling the drives physically when you install them, it is a lot easier. 1 Quote Link to comment
