Hi
I thinking of ways I can use ZFS to improve storage and system performance.
Two thinks I am interested in accounting for:
- If I mirror across drives of different read/write speeds, in brief, what effects can I expect this to have and are the any configuration options available to ensure it reads from the faster drive by default.
- If in a mirrored pool a disk becomes temporarily unavailable but later become available, is ZFS capable of synchronizing, with data that has been written to the drive remaining online been written to mirror drive when that becomes available again (even after a system reboot), e.g., if the second drive was a partition on a networked disk image (which is precisely what I am considering doing).
I realize GlusterFS is another option but I want to see is reliably possible simply with ZFS. That said, I would potentially consider going into the ZFS source later and making some updates if I find areas in which I would like to see it improved. For now though, I just want a rough idea of what to expect till I have time to investigate further.
