The adage that I adhere to with ZFS features is "just because you can doesn't mean you should!". I would suspect that with that many filesystems the normal zfs-tools would also take an inordinate length of time to complete their operations - scale according to size.
Generally snapshots are quick operations but 10,000 such operations would I believe take enough to time to complete as to present operational issues - breaking these into sets would alleviate some? Perhaps if you are starting to run into many thousands of filesystems you would need to re-examin your rationale in creating so many. My 2c. YMMV. -- Khush On Tuesday, 31 May 2011 at 11:08, Gertjan Oude Lohuis wrote: > "Filesystem are cheap" is one of ZFS's mottos. I'm wondering how far > this goes.
