You solution fixed it for me. Lost a few days of logs as well and i am on the latest commit of the XO community edition.

Theres some bug with syslog clear but your fix works great.

@olivierlambert said in file restore on large backups ends in print_req_error: I/O error's:

Yes, that sounds the next step to do 🙂 Something is wrong during the mount phase. Also check you have enough RAM in your XOA.

Ok, filesystem checks out - as far as I can see having:

Done full restore of VM from the same Delta image. Booted VM, logged in and done 'tar cvf /dev/null *' of the filesystem I'm trying to restore from - which ran to completion without error.

I upped the RAM for XOA from default 2GiB to 16GiB and re-tried - and same result.

I can try yet more RAM if needs be but would hope 16GiB is more than enough?

The console error on XOA is more detailed than my install- so don't know if this helps:

blk_update_request: I/O error, dev loop0, sector 8912912 op 0x00:(READ) flags 0x80700 phys_seg 1 prio class 0

Looks to be the same issue, just reported differently.

You also (on both systems) get kernel chatter about "tasked blocked" (understandable, as it is).

@olivierlambert said in Can't restore VM's from 'read-only' remote?:

A remote (now Backup repository) is meant to write backups into it. If you aren't able to write, then, sure, you can restore but you won't be able to backup anything.

Yes, understand that 🙂 - I'll have to re-test here, but I'm sure when it was 'read-only' - I couldn't restore anything from it, as nothing showed up in XO's "Backup / Restore' list of backups...

The remote was mounted on two systems - hence why made R/O for one of them (this was just for testing restores).

@florent

Yes, thanks!

We have very limited control over rsync at our end (as it's running within a Synoloy NAS) - I think we probably have to just live with large transfers for now - whilst looking at spit files / VHD's as the way to go in the future.

Thanks again!

I do not get this problem on XCP-ng 8.1, just to add more information.

FYI, you can always ask for another XOA trial when you need it 🙂
