[sheepdog-users] 答复: Does the SSD cache disk mount need user_attr?

[redtone]

Because when I enable the -w SSD cache the VMs will be hung up（when I
reboot the VM, the windows cannot boot but black screen）.
And I found the ssdcache does not mount with xattr on

So I found the ssdcache is not mounted with xattr on.

I have run the VMs for one week with no -w cache normally.

I am trying -w ssdcache mount with xattr on today,
I will report the result later if the issue can be duplicated.

AFAIK, the object cache feature of sheepdog doesn't require xattr. You
can turn it off if the partition isn't used for storing ordinal
objects.

BTW, do you have a reason of turning xattr off?

Thanks,
