October 5, 20178 yr I am running the trial version of UnRaid 6. Is it normal for the parity check to run daily? I looked in the schedules section in settings and there is nothing there for scheduling the parity frequency.

October 6, 20178 yr I figured that you were having random reboots (which you're not). There is nothing in Settings - Scheduler (did you scroll down?) to adjust the parity check frequency?

October 6, 20178 yr You're the proud discoverer of a bug in 6.3.5. If you don't have Parity installed (but do have Parity 2 installed), then you don't see the option to adjust the parity check times. Not in a position to see in 6.4 is affected, but @bonienl could look at the code.

Not in a position to see in 6.4 is affected, but @bonienl could look at the code. I setup my array with the option to add a second parity disk but I do not currently have a second disk. Should I change it to one parity disk? If I do that can I add a second parity disk later? Hope it is fixed soon. I have 9 days left in my trial and I think I might buy it. I don't think parity checks need to run daily. How often do you suggest running them? Edited October 6, 20178 yr by mikeyunk

How often do you suggest running them? Monthly. How you've set up your drives, while perfectly valid is out of the norm. With only a single parity drive you tend to allocate it to the first parity slot, not the second. If nothing else, the parity calculations are faster that way, and you would avoid this bug. I have no idea if this affects 6.4, and am not going to trash my parity information to test it. Maybe someone with a test server can check it out.

October 6, 20178 yr Yeah. You'll have to do a new config, and then assign parity 1 as the parity disk. It will have to rebuild the information on it. You can at any time add in the 2nd parity drive by simply assigning it to the parity 2 slot.

You can at any time add in the 2nd parity drive by simply assigning it to the parity 2 slot. So I have to switch my current parity disk from 2 to 1, but leave slot 2 open? The parity disk will have to rebuild as you said? Will I loose any data doing this? I think what I did was when I setup the array the first time I had a 3TB HDD as parity 1, then I added a 5TB drive that I decommissioned from my gaming PC and added it as parity 2. Then I removed the parity 1 3TB disk and added it to the array for more storage. Now I have 1 parity drive (the 5TB) drive and it stayed as parity 2. Edited October 6, 20178 yr by mikeyunk
October 6, 20178 yr I am not sure that the New Config is needed - I think it might be possible to just unassign the disk from the parity2 slot and then assign it to the Parity1 slot. Easy enough to try out. Regardless as long as there are no issues with any of the data disks then there is no risk to the data unless a drive fails before the new parity has been successfully calculated. All that will happen is that a new parity will be calculated based on the current contents of the data drives
October 6, 20178 yr 47 minutes ago, Squid said: I have no idea if this affects 6.4 Yes, it also affects 6.4, I would suggest to @bonienl that since it's been possible from v6.2 to do a read check without parity, and that is a good way to check the devices for anyone running a paritless server, to change the text from parity check to read/parity check and leave the option to schedule it always available independent of the parity disks.
October 6, 20178 yr In the latest version of 6.4rc (not released yet) the scheduler page has changed to give a warning when the parity disk is not installed. Currently only done for the first parity disk. I need to add a verification/warning on the second parity disk too. Thanks for the observation.
