I'm not sure if a literal date would work there, but certainly something like compat=freebsd10 or compat=ZoL0.7. Or even "compat=freebsd10&ZoL0.7", meaning only features that are supported on both. If it were a date then I think we'd need to explicitly say what the releases are, e.g. "compat=2016" is an alias for "compat=ZoL0.7&freebsd10&OmniOSr151018" --matt > (Yes, pool creation is an uncommon event for most, but IMO the default > behavior should not be to end up with a pool no other platform can > import.) > > But that's just me having had to explain to many people why their pool > wouldn't import elsewhere when a bug on one platform bit them and they > wanted to try another. > > - Rich > On Wed, Nov 28, 2018 at 6:36 AM Igor Kozhukhov <i...@dilos.org> wrote: > > > > Hello All, > > > > could you please let me know : what are problems with ZFS on Linux, > FreeBDS, OSX and others ports? > > > > For example: > > on Linux we have problems with poweroff - pool can be unavailable and > need some dance for restore it (with lustre node, etc) > > > > what are problems with ithers? > > > > best regards, > > -Igor > > > > ------------------------------------------ > openzfs: openzfs-developer > Permalink: > https://openzfs.topicbox.com/groups/developer/T1ce8db6589272d89-Ma2240404d27f5c96e37f8a47 > Delivery options: > https://openzfs.topicbox.com/groups/developer/subscription > ------------------------------------------ openzfs: openzfs-developer Permalink: https://openzfs.topicbox.com/groups/developer/T1ce8db6589272d89-M89f0ab3dead11ff8071ccec5 Delivery options: https://openzfs.topicbox.com/groups/developer/subscription
