XCP-NG/XenServer tapdisk error

travisdh1

Running into the tapdisk error when trying to create new VMs on my XCP-NG server. All the issues I see online point to a drive vhd error or unreadable optical media for the VM.

The server is able to read and write to the SMB ISO library when I browse to /run/sr-mount/sr-uuid.

This is a brand new VM, so no booting without the ISO library working.

Anyone else run into this issue and figured it out?

I have not had this issue yet.

It's a bug... see https://mailchi.mp/7ed52f9a2151/important-noticeopenvswitch-issue

~~Maybe a permission thing on the ISO library?~~

What is the exact error?

I updated this but I had not seen the issue before.

I had seen that an update for openvswitch was available last night. I bet that's my issue. Now I just need to clear some temp files to actually install the patch.

. -name "var/log/ovsdb-server.log.*" -print0 | xargs -0 rm

This took care of it for me. The bug was creating a billion log files

Yeah, when the problem mentions running out of inodes, that's almost always the issue. I had not so fun times with IRIX bugs that caused the same sort of thing back in the mid 90s.

Sure enough, that was it.
