zfs discuss - Mar 2010 - Problem importing a pool consisting of mkfile elements

Hi,

When creating a zfs pool with mkfile components in S10 10/09, I was testing the
export/import feature (I did it in Solaris 11/06 and it worked well).

But it didn''t work. I tried the -d /dir option without success.
It didn''t work any better with the zpool destroy and zpool import -D
succession of events.

Is is a removed feature ? I know that it''s better to work with whole
disks.

By the way. Is there a way to move the files to another system and try to import
them on the target system ? (I guess this is no :-))

Thanks for your answer.

I would not like to be classified as a spammer. But can anyone help me about
this ?

If mkfile-created pools cannot be re-imported, it may be a concern to some
customers.
Thanks for a reply.

Hi Marlanne,

I can import a pool that is created with files on a system running the
Solaris 10 10/09 release. See the output below.

This could be a regression from a previous Solaris release, although I
can''t reproduce it, but creating a pool with files is not a recommended
practice as described in the zpool.1m man page.

You are correct also in that you cannot import a pool that is created
with files on another system. I don''t think this operation was ever
intended to be used on a pool that is created with files.

Thanks,

Cindy
