Add ZFS runtime compatibility check
dellgreen opened this issue · comments
Check if files we are working on reside on a ZFS file system, if they do check that the ZFS kernel module parameters are configured to be compatible for our usage, otherwise processing will fail.
If on a ZFS file system, check /sys/module/zfs/parameters/zfs_dmu_offset_next_sync is "1" and not "0"

@dedekind I'm not a python developer, but, had a quick look at Filemap.py, it looks like a good place to do the check is in the _FilemapBase class constructor, as we have a path to the image file there already and both subclasses can inherit the check, do you agree?
Yes, sounds like the right place. And no worries, this was my 2nd Python program, so the code is more or less naive and straightforward.
where do i declare test dependencies in python? i assume if i import anything new into a test then the build will fail on github when the code coverage is ran?
I think this issue can be closed now :)
