Hello, I''m new to ZFS and I would like to clarify this to you. Having 2 HDDs and one striping ZFS pool(data lost is not an issue) on them what is best to use for storage folders in this pool or new zfs? I need 4-5 majors folders which will contains lots of sufolders and I don''t know if it''s better to creade 4 new folders in my pool or 4 new zfs. Thank you very much!

That depends on the pool which is already shared by them. If there''s ever a chance that you''d want different quotas between them (or space reservations), or want different snapshot policies, then creating them as separate filesystems seems to make sense and give you somewhat more flexibility. If you had hundreds, then the overhead of managing all those filesystems might be annoying. At four, I wouldn''t worry about it as much. -- Darren Dunham ddunham at taos.com Senior Technical Consultant TAOS http://www.taos.com/ Got some Dr Pepper?

However due to some bugs which are not fixed yet in some cases it would help if you create more file systems like if your applications issues fdsync on a file and there''re more writes pending to other files. It''s only 4-5 file systems - I would probably create file systems instead of directories. And with zfs you don''t have to think which one will need how much space in advance which is really great. -- Best regards, Robert mailto:rmilkowski at task.gda.pl http://milek.blogspot.com
