  1. [SOLVED] Re: Seemingly sporadic slow ZFS IO since 22.04

    Dang. That took a while. I was wondering if everything was okay...

    Crossing fingers with you!!!
  2. [SOLVED] Re: Seemingly sporadic slow ZFS IO since 22.04

    You could check with du right? Using the '--exclude' flag
  3. [SOLVED] Re: Seemingly sporadic slow ZFS IO since 22.04

    LOL. Yes.
  4. [SOLVED] Re: Seemingly sporadic slow ZFS IO since 22.04

    The -r flag on zfs snapshot means recursive. That will create snapshots recursively of the current and all descendent datasets underneath what you asked for.

    The -R flag on zfs send will will...
  5. [SOLVED] Re: Seemingly sporadic slow ZFS IO since 22.04

    You would use either a full snapshot with Send/Receive... Or an rsync backup to somewhere. Both are not needed. Right? That would result in two "separate" backups of the same thing. I mean, that...
  6. [SOLVED] Re: Seemingly sporadic slow ZFS IO since 22.04

    It needs to write as new so if not destroying the pool, then destroying the filesystem dataset within the pool would get rid of the data written to it. Then you would not have to recreate the pool...
  7. [SOLVED] Re: Seemingly sporadic slow ZFS IO since 22.04

    To give you a peek at some of that going on...

    If I do this:

  8. [SOLVED] Re: Seemingly sporadic slow ZFS IO since 22.04

    How long was it faulted before you changed in the new drive?

    If a drive is faulted, then it stops adding new to that drive, but continues to write to the others, causing an imbalance between the...
  9. [SOLVED] Re: Seemingly sporadic slow ZFS IO since 22.04

    I'm starting to see a pattern there...

    First, this is what these columns mean:

    Look at the consistently high values for /dev/sdf1 in those two columns. That disk is only 1 disk in an 8 disk...
  10. [SOLVED] Re: Seemingly sporadic slow ZFS IO since 22.04

    Dang! It's trying to hide from us... LOL.
  11. [SOLVED] Re: Seemingly sporadic slow ZFS IO since 22.04

    Thank you. Very curious in seeing those samplings. They should be small enough to upload as text file attachments. But if not, then upload them to pastebins at paste.ubuntu.com with an expiration set...
  12. [SOLVED] Re: Seemingly sporadic slow ZFS IO since 22.04

    The thing I have a problem grasping, is that the process of what you are doing (watching something from your media server) is a read process. Why is the read speed high, and the write speed so low?

  13. [SOLVED] Re: Seemingly sporadic slow ZFS IO since 22.04

    "The Force is strong in this one..."

    Still here. I'm not having that problem. (Yet.) I did have some other strangeness. Which was odd and I cannot explain a why for it, really.

    It lost track...
  14. [SOLVED] Re: Seemingly sporadic slow ZFS IO since 22.04

    No problems. This is in your own time. LOL.
  15. [SOLVED] Re: Seemingly sporadic slow ZFS IO since 22.04

    Glad to hear everything is going so well.
  16. [SOLVED] Re: Seemingly sporadic slow ZFS IO since 22.04

    Happy New Year!

    Good to see all is well and holding!
  17. [SOLVED] Re: Seemingly sporadic slow ZFS IO since 22.04

    Happy Holidays to you and your's!
  18. [SOLVED] Re: Seemingly sporadic slow ZFS IO since 22.04

    So far, so good. Still crossing fingers. LOL
  19. [SOLVED] Re: Seemingly sporadic slow ZFS IO since 22.04

    LOL. Still crossing fingers...
  20. [SOLVED] Re: Seemingly sporadic slow ZFS IO since 22.04

    Open Settings.
    Select Appearance in the sidebar.
    Click 'configure dock behaviour' in the Dock section.
    Slide the 'Show Volumes and Devices' toggle to off.
  21. [SOLVED] Re: Seemingly sporadic slow ZFS IO since 22.04

    Let's see how this pans out over a few days...
  22. [SOLVED] Re: Seemingly sporadic slow ZFS IO since 22.04

    I don't see anything jumping out at me.
  23. [SOLVED] Re: Seemingly sporadic slow ZFS IO since 22.04

    I do the same (with install recipes) of all the commands I used to create someting, and the output, so I have a record of, and can track how it was, and changes I made to things.
  24. [SOLVED] Re: Seemingly sporadic slow ZFS IO since 22.04

    I would have the same guess. You just replaced the cables.

    ZFS "zpool status" logs and shows read, write and cksum errors. It hasn't been showing those has it?

    I tend to pay more for Samsung...
  25. [SOLVED] Re: Seemingly sporadic slow ZFS IO since 22.04

    I'm thinking about if you installed sysstat and did something like this:


    # syntax: pidstat -d <interval> <times>
    sudo pidstat -d 30 59 | tee -a $HOME/pidstats.log

    Then it might track some of...
