its still there ie the host is still atached to that vdi

im thinking this is the issue why my backups wont run anymore

if not i will do it on the xen server cli, but it would be nice to know why this isnt working

thanks Olivier,

i thought while im having this nightmare i mightaswell update my XOA at the same time

so if XOA auto unplugs the vbd to the vdi, why is it throwing errors?

haha, i just want to kill myself

vbd.delete

}

so its still attached to my DOM0 ie xenserver the host itself

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

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?

great, seems a bug in XS 7.6 and im running it LOL

https://github.com/xcp-ng/xcp/issues/104

jaroslaw-freus created this issue in xcp-ng/xcp

closed XCP-ng 7.6 /run/lvm/lvmetad.socket: connect failed #104

mmm... not looking good, got a problem with my backend SR...
