says can't because disk is mounted, but can't get to the rest of the pool if its unmounted
-
it appeared to have gotten further, and I believe I now have both cache drives in SATA slots, diagnostics included to confirm.
Nothing I can do to possibly limp it along to get a copy of the contents? Some of it? all of it?
like I said, all I really want is my VMs ...specifically one of them.
after that, I don't mind decomissioning the bad SSD and formatting the remaining one as cache. I already have a new 2TB en route.
-
I think the device dropping issue is probably symptomatic of the drive dying, in which case, what could I really do about it? Having said that, I'll shuffle the drives around again, and send another diagnostics. In the mean-time, If-after I shuffle the cache drives to both be on SATA the device still drops, is there something I can do after that to attempt to copy data off?
-
To reiterate,
I would love for there to be some kind of method to just change the pool back to using a single drive (the 1 of 2 drives in the cache pool still good). Of I would be willing to buy a new 2TB SSD to replace both drives in the pool.
At this point, I would just like some way (ANY. way.) - that would allow me to at least copy off whatever files are essential - especially my VMs.
Is there anything I can do here?
-
well based on your original response, I rearranged my cache drives to what I thought was the LSI. Can you confirm?
and I feel like I'm coming across as dense, but which are my intel ports? -
you're absolutely right, and I'm perfectly willing to try. I'm just wondering which log you got that from, so I can look at the previous diagnotics and see if either cache drive was previously in an LSI to narrow down what ports I could try, then self-verify so I can follow your advice and get both of them on an LSI controller.
-
I guess I don't understand how one SSD appears to be connected differently than another SSD. It's a single backplane, and both are connected to the same backplane. Perhaps in my previous diagnostic, one of the drives was hooked up to an LSI controller then as well? If I knew which was was on the LSI controller both then and now I can perhaps shift them around so they are both in a slot previously recognized as LSI. If-not, which part of the diagnostics would I look at to see LSI vs SASLP?
-
also, I have a HUGE PlexMediaServer folder on cache that I wouldn't be upset about if I trashed all together. Would it help - or make it worse - or change nothing?
-
I keep rebooting and scrubbing ....sometimes it gets father, sometimes not. Shall I continue, or is there a better approach?
-
I have a backplane, so I can't really plug directly into the board, but I switched the slots for both cache drives, and the corrective btrfs scrub started fine, then aborted.
-
wow I'm such a rookie! Apologies, see attached.

So I have a cache pool /dev/sdj and /dev/sdk and /sdj is throwing errors, so probably going bad. For a minute, restart I was able to get it to be recognized and come online, and I stupidly missed my window to copy my windows VM from within.
At this point, if I spin up the array normally, the cache pool will say "no file system" seemingly no matter what. Whatever section of /sdj1 that's bad is right in the section where mover needs to move, so I can't move anything. I also can't run dockers, as they were built dependent on cache, so no krusader. I found a link here which allows me to make the cache pool read only, which lets me look at things via console.
btrfs rescue zero-log /dev/sdj1
I've attempted multiple variations of rsync to copy the vdisk.img to a location on the array, all of which fail. The latest being
rsync -avh --progress --sparse /mnt/user/domains/Windows\ 10/vdisk1.img /mnt/user/Archives/VMBackup/Win10/
which results in the following (bear in mind only 200G is allocated to that VM):
214.75G 100% 63.13MB/s 0:54:04 (xfr#1, to-chk=0/1)
rsync: [sender] read errors mapping "/mnt/user/domains/Windows 10/vdisk1.img": Input/output error (5)
WARNING: vdisk.img failed verification -- update discarded (will try again).
214.75G 100% 51.68MB/s 1:06:02 (xfr#2, to-chk=0/1)
rsync: [sender] read errors mapping "/mnt/user/domains/Windows 10/vdisk1.img": Input/output error (5)
ERROR: vdisk1.img failed verification -- update discarded.
I also tried
cp -av --sparse=always <source> <destination>
'/mnt/user/domain/Windows 10/vdisk1.img' -> '/mnt/user/Archives/VMBackup/Win10/vdisk1.img'
cp: error reading '/mnt/user/domain/Windows 10/vdisk1.img': Input/output error
I'm at a loss. Any advice? Honestly, if I could remove the pool, and put all of cache on /dev/sdk1 then I'm sure all would be well.

I was havig trouble with my Win7 VM not trimming and after a post here this lovely community guided me in the right direction and I ended up spinning up a Windows 10 VM so I could attempt to avoid the trimming issue in the future. I followed the post that was linked in that thread, and after some troubleshooting, ended up having to use SeaBIOS to create my VM. I gave it meager hardware stats as it was part experimenting and part if-this-works-this-is-what-i'll-use. Now that it's up and running, I'd like to give it more cores and more RAM, but whenever I shut down the VM and go edit the settings, no matter what I change, it says I have more than one SCSI channel indexed as 0. Can anyone give me some directionon how I can alter this VM and give it more processors and RAM?

well that sure enough worked! thank you to everyone for the help!
Will this be a reoccurring problem though? It took most of the day to copy off the img file then copy it back due to it being ~500G. Which leads me to an off-topic question, if I decided to change my cache from RAID1 to RAID0, will I need to empty off the cache drive first?
-
crap. So did I mess things up with my copy command? If-not, I should adjust steps 2 and 3 to be /mnt/user/vDisks rather than /mnt/cache? Do my steps and syntax look correct (other than /mnt/cache)?
-
ok I made a share called vmbaktemp, and since this copy is going to take a while, I just want to make sure I have my order of operations down so I'm not leaving anything out.
- cp /mnt/cache/vDisks/win7/vdisk1.img /mnt/user/vmbaktemp/vdisk1.img
- rm /mnt/cache/vDisks/win7/vdisk1.img
- cp --sparse=always /mnt/user/vmbaktemp/vdisk1.img /mnt/cache/vDisks/win7/vdisk1.img
...and I don't need to run any other trim commands or anything else, yes? Sorry, not trying to be a nuisance, just trying to make sure I understand the instructions properly.
-
Please excuse my ignorance, I'm guessing the cp = copy meaning I'm copying the vdisk1.img? In that case, I don't have enough free space to make a duplicate copy of it, or am I misunderstanding?
-
It appears the instructions layed out there are specifically with Windows 8/10 in mind. In my case, my VM is Windows 7, do the same instructions apply, or would I be better served just renaming like the post mentions?
-
The size of the vm is what I expect it to be, I don't see how I'm missing those 300G. The single windows vm size on disk is 550G which is what I set it to.
-
I don't think I'm understanding how the cache works or something. I have 2 1T drives in a cache pool, and the server registers that as 980G total, which is fine. My problem is my cache keeps filling up now and I appear to be missing more than 300G of storage from the cache drive. Please forgive my formatting. I don't know how to format it to be more readable, so I did the best I could. At this point, I'm thinking I may attempt to convert it to raid0, but even then I'm not sure if I'd have to empty the cache drive of its contents (which I'd like to avoid if-possible). At this point I'm looking to understand how more than 300G goes "missing" and how to get it back.
Essentially am I not understanding some kind of math here, or how the cache operates or something?
- du -sh /mnt/cache = 600G /mnt/cache
so where am I being mistaken? It seems to me that 980-600=380 and I would even allow for some overhead, but 300G?? Can someone point me in the right direction here?

if I remove them both, array greys out "start array", unless I commit to them being out ....makes me nervous. Would it be better to wait for my replacement cache drive to arrive?
or if I do unassign them, can I then put them back in case something goes wrong?
