Hi, I have the following configuration: ~>uname -a FreeBSD XxX 11.3-STABLE FreeBSD 11.3-STABLE #1 r354607: Mon Nov 11 12:19:28 CET 2019 root@jedi:/usr/obj/usr/src/sys/HP amd64 ~>zfs list NAME USED AVAIL REFER MOUNTPOINT zroot 244G 0 10.7G /mnt zroot/Centos8 6.80G 4.13G 2.67G - zroot/msw7 44.9G 25.8G 19.1G - zroot/swapdisk0 40.8G 20.6G 20.2G - zroot/usr 131G 0 50.9G /usr zroot/usr/home 80.1G 0 80.1G /usr/home zroot/var 9.94G 0 9.94G /var After zfs snapshot, which I did on the root, I got: ~>zfs list -t snapshot NAME USED AVAIL REFER MOUNTPOINT zroot@200909 1K - 10.7G - zroot/Centos8@200909 1K - 2.67G - zroot/msw7@200909 1K - 19.1G - zroot/swapdisk0@200909 0 - 20.2G - zroot/usr@200909 1K - 50.9G - zroot/usr/home@200909 1K - 80.1G - zroot/var@200909 1K - 9.94G - i.e. whole filesystem is read only. I am not able to do neither rollback, nor destroy of the snapshot. Is there any possibility to reset the filesystem to the read-write mode? Any help is greatly appreciated. Regards, lk
