    Please post the diagnostics: Tools -> Diagnostics, though the problem is likely the same as the already reported Marvell issue with v6.7:
  3. JorgeB
    The cache SSD got disabled, there's an issue with Marvell controlleres and v6.7, it might work if you disable vt-d.
  4. JorgeB
    I believe md_num_stripes can make a difference but the other ones should only affect parity sync speed.
  5. JorgeB
    If the budget allows it and assuming you have another PCIe slot, get a SAS3 LSI like the 9300-8i plus a SAS3 expander like the Intel RES3TV360, that together with your existing LSI will give you enough ports with lots of bandwidth. If that's too expensive get another SAS2 HBA like the 9207-8i and an Intel SAS2 expander like the RES2CV360, a little less total bandwidth but miles better than the RocketRAID, both in terms of speed and more importantly much more reliable.

    Work, yes, recommend no, besides being a Marvell chipset, same as the SAS2LP, and a known source of issues, it also uses 4 SATA ports multipliers, another no-no, also performance won't be good.

    BTW, also tested on Arch Linux with kernel 4.20, latest mpt3sas v26.100.00.00, no change.

    Unrelated to your issue, but disks3 had some media errors, you should run an extended SMART test.

    If I have the time I'll try to do some tests over the weekend with >100GB files.

    Maybe, weird that I don't have issues with send/receive sending TBs of data over SMB, but since it works at the block level it might behave differently, at what file size did you notice the issue?
  11. JorgeB
    I'm not sure how this can happen, by default Unraid uses 20% free RAM for write cache, after that is filled the transfer will slow down to the speed the server can actually write to the devices, it will (or it should) never use more than 20% of RAM for write cache, at least not without the user changing the defaults, I can't see how the server could still be writing 10 or 20 minutes after the transfer finishes, but maybe someone else will have some ideas.
  12. JorgeB
    I don't usually transfer files that large, though files of about 50GB I use quite frequently and never had issues, but for sure don't have a problem transferring various TBs over SMB with btrfs send/receive, that's a continuous stream, last one took almost 24 hours, without any issues, memory usage doesn't go above 20% with 16GB installed, if no one else has any ideas I'll do some tests with a 100GB file over the weekend. Edit: I forgot I have screenshot from the last one I took because of an unrelated issue, and it was 17hours, not 24.

    Then hopefully someone with the same board will confirm if it's a general problem or not.

    If you mean trim with a SAS2 LSI It doesn't, I already checked, it's in this thread.
  15. JorgeB
    I would say that for now, and likely for the foreseeable future, these are the options to get your SSDs trimmed: -Use the onboard SATA ports, it works with any SSD -if your SSDs support determinist trim and you really want to have them connected to the HBA get a SAS3 LSI, like the 9300-8i.
  16. JorgeB
    I had already mentioned that, only prior models don't have that. https://forums.unraid.net/topic/74493-samsung-ssd-hba-trim/?do=findComment&comment=720637

    It didn't make sense if it was, but just to confirm this isn't an Unraid problem, I installed latest Fedora workstation, it comes with mpt3sas v25.100.00.00, same an Unraid v6.6, and get exactly the same cryptic error when trying to trim a supported SSD with a SAS2 LSI: FITRIM ioctl failed: Remote I/O error
  18. JorgeB
    Don't have any Asrock boards, but IPMI works fine with Supermicro boards and v6.7, did you check for bios and/or BMC firmware updates?
  19. JorgeB
    There would still be complaining that it doesn't work, and that's what I can't find with other Linux users.
  20. JorgeB
    If getting a new one get any LSI with a SAS2008/2308/3008 chipset in IT mode, e.g., 9201-8i, 9211-8i, 9207-8i, 9300-8i, etc and clones, like the Dell H200/H310 and IBM M1015, these latter ones need to be crossflashed.
  21. JorgeB
    Agree, for me the only strange thing about this is trim no longer working with LSI SAS2 HBAs now for over a year or two, even when using the required SSDs, it appears to be a Linux driver issue, but I did a lot of googling and can't find any info about it or other people complaining.
  22. JorgeB
    Most are, and all 4TB models are for sure.
  23. JorgeB
    Like I already mentioned btrfs snapshots are read only, can't be infected/modified/deleted.
  24. JorgeB
    Docker image is corrupt, delete and recreate, you should also post the diags as it might show why it happened.
  25. JorgeB
    Sorry, I wasn't very clear, if you run sg_unmap on the whole device it will wipe it completely, like running blkdiscard, not like fstrim that only unmaps the sectors marked as empty, at least that was what happened when I did it, feel free to try but do it on an empty SSD. To install download the package and put in inside a folder called "extra" on the flash drive, Unraid will then install it at every boot.
