Hi, I want to know why zpool import cost a long time or hung? and how to fix it? thanks.
It might take some time to "think", in particular about delayed operations (i.e. large dataset deletions which were just marked as deleted, and then lots of metadata has to be raked through to actually free up the space - especially lots of work for some deduped datasets); this can be somewhat tracked by "zdb -bbLC pool" or somesuch (takes a minute to get the metadata) - see the progress and (non-zero-ness at all) of "Deferred free" and similar entries. Some more info can be gleaned with "iostat" to see if any disk io occurs (maybe lots of random slow ios).
