I have 3 pools. 2 of them are mirrors, another one single. Doing zdb -m pool I got messages "space map refcount mismatch: expected 116 != actual 115". Looked at github issue #3094 there are no solution to fix it. And I don`t know is it dangerous.

Interesting does anybody else was this issue ?

Code:
zpool list |grep -v NAME | cut -d' ' -f1 | while read POOL; do echo $POOL; echo $(zdb -m $POOL | grep mismatch); done

# zpool list | ......
nmz_zfs
space map refcount mismatch: expected 116 != actual 115
rpool

zfs_mirror
space map refcount mismatch: expected 107 != actual 106


p.s. My pools are created after fresh Proxmox 4.0 install.
 
Maybe for today but you never know what will be tomorrow.

I follow zfs mailing list and starting zfs 0.6.4 with new features flags there was a lot of problems. I think 0.6.3 was most tested version. Now I`m recreating pools with disabled most of the feature flags.
