Title:
fstrim not working with image mounted to path?
Status in QEMU:
Expired
Bug description:
guest os: windows server standard 2016
qemu agent version 100.0.0
os supports trimming
path mounted image does not support trimming
C:\Users\Administrator>fsutil behavior query disabledeletenotify
NTFS DisableDeleteNotify = 0
ReFS DisableDeleteNotify = 1
[@ ~]# virsh qemu-agent-command vps-xxx '{"execute":"guest-fstrim"}'
{"return":{"paths":[{"path":"C:\\"},{"path":"C:\\Program
Files\\Microsoft\\Exchange Server\\V15\\Mailbox\\xxxx\\","error":"The given
volume path is invalid. (0x89000001)"}]}}
Looks like the fstrim does not like/check images mounted on a path? Nor
detects if image trimming is supported. xxxx is a ReFS mounted image without
trimming support.
If I enable trimming on the ReFS image, and configure it win2016, the
result is still the same.
C:\Users\Administrator>fsutil behavior query disabledeletenotify
NTFS DisableDeleteNotify = 0
ReFS DisableDeleteNotify = 0
[root@c03 ~]# virsh qemu-agent-command vps-xxx '{"execute":"guest-fstrim"}'
{"return":{"paths":[{"path":"C:\\"},{"path":"C:\\Program
Files\\Microsoft\\Exchange Server\\V15\\Mailbox\\xxxx\\","error":"The given
volume path is invalid. (0x89000001)"}]}}
PS. tried this on a win 2016 std server with just one fs, no problems
then.
