MAP_DUPLICATE_KEY error in XOA backup - VM's wont START now!
-
Hi,
I would check on your NFS server, I suspect some disconnection happened causing your tapdisk to hang.
dmesgmight provide some useful info.In any case, you can always shutdown the VM, reset the VDI state and boot it again without any issue. Feel free to open a support ticket to have assistance on your supported infrastructure.

no errors on the storage , already checked those logs on the NFS server. all other 400+ VM's are working fine , and backup ran fine fine for them last night. only ones that failed are in this state.
VM was shutdown, and the vm we shutdown in this state will not start back up with error:
SR_BACKEND_FAILURE_46(, The VDI is not available [opterr=VDI 3a4bdcc6-ce4c-4c00-aab3-2895061229f2 not detached cleanly], )when we reset the VDI state we get :
"vdi not available now" -
I'm talking about the
dmesgof the Dom0. -
dmsg on the master just shows the typical
example : hour and hours of:

You have an issue indeed, because the
dmesgis showing something that shouldn't happen. And it seems to be I/O error related, explaining your problems. Asking around if I can have a better meaning than that. -
still doing more digging on our side too
the issue seems to be around here:

c305769c-bb8a-43f4-88ff-be7d9f88ad1b is fen-xcp-08I can't really see what 93c10df0-ba2a-4553-8e3e-43eb9752fba1 is; I would think a vdi, but it's not showing as so. no tap-disk process attached to anything with that in the name,
-
My first feeling is a I/O issue causing the process to hang, because the device
tdlisn't responding anymore. Reasons could be numerous, network (packet loss or whatever), process issue on the NFS server but as a result, the underlying process attached to this VDI was dead.To answer your question, 93c10 is the parent VHD (in a snapshot chain). You need the parent to be reachable to coalesce.
-
... that helps in that I know that 93c10 should be findable; but if it's not , it's not immediately apparent what to do.
I suppose that I could look to try and see any tap disk that we don't know what it might be attached to.
we just double checked our storage network. Monitoring software (snmpc and zabbix) show there have been no connectivity issues over the past 6 months. no traps , no issues, steady numbers on bandwidth used.
running a constant ping shows no drops. everything storage network is layer2 connectivity. NFS are connected via redundant 40gb/s to redundant 40gb/s switches. no routers involved.
387 VM's backed up correctly, 7 failed with this error that we cant resolve.
we are not seeing any other IO issues on VM's
i can create new snapshots in the pool with no issues on other VM', backups for other VM's did complete with no errors last night except for the 7 we are having problems with.
my storage guy has finished combing through the logs on all 3 NFS servers and not finding any signs of problems with drives, network, ZFS.
also note: the issue with the 7 vm's having problems exist on across different xen hosts AND different storage NFS servers.
all 7 vm's are stuck with at least one disk in VDI to coalesce , same error/issue on all of them

Again as I said, for such advanced investigation, you should open a support ticket. Hopefully, all your involved hosts are under support so our storage team could investigate more in depth what's going on.
-
Was a solution to this issue found? I am not running into the same thing in my home lab after my nightly delta and monthly full backup ended up running at the same time. i have 2 VM's each with a disk in the same state as the original poster.
-
@SeanMiller Have you tried running the
resetvdis.pycommand on the affected VDIs? You can read more about it here. -
@Danp sure did, it was no help. we ended up having to restore the effected VM's from backup
there was no sign of any storage network issues during the time this started, no RT,RX errors anywhere, no traps, nothing in the zfs server logs.. nothing.... we have hundreds of VM's running , only 7 were effected and at random times during the backup process. its a little concerning..
-
-
@SeanMiller no sorry, we ended up having to restore the VDI's form a known good backup.
-
Im restoring from backup.
This does have me a bit concerned, This type of issue should not be caused by a backup..
-
The root cause is not clear, I don't think it's the backup directly. It might be the generation of snapshots and reading them that cause a lot of sudden I/O on the storage.
This would require some intensive investigations, gather all the logs of all hosts and inspecting what's going on. Each installation is unique (hardware, network, disks, CPUs, memory, there's an infinite number of combinations), so finding a solution on a forum without spending days asking tons of questions seems complicated. What's concerning to me is that type of infrastructure should not be unsupported, because spending time to understand the problem is part of what we do. I'm not saying we'll find magically a solution or the root cause, but at least it could be investigated in details and compare if we have similar reports to go deeper.

@olivierlambert I can provide information on infrastructure if it would help. the issue has not happened again though , and i cannot re create the issue in my lab. even when backups are running we are REALLY under utilizing our NFS/ZFS NVME/SSD based storage with 40gb/s links. i'm not saying its not possible, but i would be shocked. we have no recorded tx/rx errors on truenas/swtich/hosts and no record of any snmp traps coming in for any issues with all the equipment involved.

and its happening again tonight.
I have 55 failed backups tonight with a mix of the following errors.
Error: INTERNAL_ERROR(Invalid argument: chop)
Error: SR_BACKEND_FAILURE_82(, Failed to snapshot VDI [opterr=failed to pause VDI 346298a8-cfad-4e9b-84fe-6185fd5e7fbb], )Zero TX/RX errors on SFP's at on XEN hosts and Storage
ZERO TX/RX errors on switch ports
no errors on the ZFS/NFS storage devices
no traps in monitoring for any networking or storage issues. -
Well, obviously something is wrong somewhere, otherwise you wouldn't have this error. I think I never saw
Error: INTERNAL_ERROR(Invalid argument: chop)in my life.There's something triggering storage issues, not having TX/RX errors doesn't save you for other problems, like MTU problems, bad switch config or simply latency issue from the Dom0 perspective, you name it. I'd love to get it reproducible at some point but as you can see, there's "something" that makes it happen, now the question is "what". Those problems are really hard to diagnose because it's often a combo of environment and tipping points from timeouts or similar things.

@jshiells Did you also check
/var/log/kern.logfor hardware errors? I'm seeing qemu process crashing with bad RIP (Instruction pointer) value which screams for a hardware issue, IMO. Just a 1-bit flipping in memory is enough to cause unpleasant surprises. I hope the servers are using ECC memory. I'd run a memtest and some CPU stress test on that server.Some years ago, I had a two-socket Dell server with one bad core (no errors reported at boot). When the Xen scheduler ran a task on that core... Boom. Host crash.
