I'm using it on laptop. One pool holds OS + home directories and other more-or-less fast changing stuff.
Another one holds only backups and VM images. First reason was to try deduplication on VM dataset without affecting main pool. Second reason was to have two big partitions to do experiments - so if necessary one pool can be moved to external HDD, partition can be formatted and used as Windows or any other way. Having one single big partition spanning whole disk proved to decrease flexibility in trying new versions of OS/other OSes and etc. >From your message I hear that for NAS/storage systems this is not recommended >scenario. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to zfs-linux in Ubuntu. https://bugs.launchpad.net/bugs/1731735 Title: zfs scrub starts on all pools simultaneously Status in zfs-linux package in Ubuntu: Incomplete Bug description: # Environment Description: Ubuntu 16.04.3 LTS Release: 16.04 Linux 4.10.0-38-generic-tuxonice #42~ppa1-Ubuntu SMP Mon Oct 30 20:21:41 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux zfsutils-linux 0.6.5.6-0ubuntu18 amd64 # Current behaviour `/usr/lib/zfs-linux/scrub` starts `zfs scrub` on all pools at the same time. If pools are located on the same disk - scrub performance degrades badly. # Proposed behaviour * simplest one - start scrub of one pool after another scrub is finished * advanced - detect pools which are located on the same disk and start scrubs on them sequentially, if they are on different disks it is fine to run them in parallel To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/zfs-linux/+bug/1731735/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
