too many VDI/VHD per VM, how to get rid of unused ones
-
just out of interest when i change the magnifying glass to "type:VDI-unmanaged"
it lists "base copy"
what are they?
-
They are the read only parent of a disk (when you do a snapshot, in fact it creates 3 disks: the base copy in read only, the new active disk and the snapshot).
If you remove the snapshot, then a coalesce will appear, to merge the active disk within the base copy, and get back to the initial state: 1 disk only.
-
so can i delete the "type:VDI-snapshot"
-
This post is deleted! -
- Please edit your post and use Markdown syntax for code/error blocks
- Rescan your SR and try again, at worst remove everything you can, leave it a while to coalesce and wait before trying to remove it again

got the command
xe vm-disk-list vm=(name or UUID)
im going to cross refernce it with this
xe vdi-list sr-uuid=$sr_uuid params=uuid managed=true
and any vdis that dont match im going to delete with
xe vdi-destroy
is this corect?
mmm... when i run a
xe vdi-list
i see i have a lot of base copies
what are they all about?
-
ok Olivier
as XOA isnt working can i do it from the cli of xen, so -
xe vdi-destroy uuid=(uuid of orphaned vdi )
-
It's not XOA that's not working. XO is the client, sending commands to the host. You had a pretty clear error coming from the host, so the issue is there.
Also, please edit your post and use Markdown syntax please, otherwise it's hard to read.
-
Hi Olivier, do i need to do this -
-
Why? How it's related? Have you cleaned the maximum number of VDIs?
-
no...how do i do that Olivier
do you mean delete the orphan ones?
-
Yes, removing all possible orphaned VDIs
-
mmm... not looking good, got a problem with my backend SR...

great, seems a bug in XS 7.6 and im running it LOL
-
@robert-wild I'm not sure about that. See this comment https://github.com/xcp-ng/xcp/issues/104#issuecomment-449381556
-
so i know my continous backup replicas arnt happening because it cant do a coalesce any of my VDI's
WARNING: Failed to connect to lvmetad
so if i run this command in my xen server 7.6
vgchange -a y --config global{metadata_read_only=0}
the next time my xen server does an auto coalesce any of my VDI's, will it become good again?
-
think i have answered my own question -
basically dom0 is protecting the source vdi until vbd operations complete but theres nothing to complete
you think this is worth a shot
-
This is already something visible in Xen Orchestra, in Dashboard/Health view, we exposed all VDI attached to a control domain, it's one click to solve it.

haha, i just want to kill myself
