    Drives Missing When HBA is Moved To Another PCIe Slot

    Hi, I have several drives connected to a AsRock X470D4U motherboard (3 PCIe slots) using HP H220 HBA (MPT2BIOS-7.39.02.00, IT mode) and SuperMicro BPN-SAS-216A backplane. The drives are configured into a ZFS array in Ubuntu 19.10, and `lsblk` and `zpool status` both shows all the drives as...

I am unfortunately quite disappointed by the performance of the resulting system. I apologize for the long post, but I will try to give all relevant info that...

    Hi guys, I'm trying to identify a good method of conducting a 2 way sync between a ZFS (OmiOS) array and a remote windows owned hardware array. Both have nfs and samba shares. The arays are around 20TB in size with 16TB utilization. Please don't tell me to switch the hardware windows machine...

    Check efficiency of lz4 compression in ZFS

    Hi, is it possible to see the real space usage of a file in ZFS when e.g. lz4 compression is enabled? When I do a ls -l of a folder it looks like it shows the non-compressed size (or compression is completely ineffective for those files) though. Anyone already hampered with that kind of stuff...

    rsync or cp creates trivial ACLs on the destination

    Is there a way to suppress this? I mean so far as I see these (almost full rights for owner@, read_attr_set for group@ and everyone@) they will not really hamper with anything but with a bit of OCD that looks horrible in my neat designed group-based ACLs. Copying data onto the folders via...

    Checking complete disks for errors in OmniOS

    Hi, I just upgraded my server rack with a few more drives, now as 12TB per disk is a lot of space I wanted to check them thoroughly for errors before actually using them. On windows I know of several tools to do that but have no experience/idea for Solaris/OmniOS. What do you usually do for...

    SOLVED: duplicated zpool via send/recv, disk usage appears to be incorrect

    Solution in post two. TL;DR: it was the compression (which is, of course, almost perfect on a file filled with zeros). I'm trying to find a way to create duplicate zvols (e.g., from a gold VM) without using cloning, which would cause a dependency issue (I'd rather be able to delete the parent...

    Cache plans for ZFS server

    So I have taken the plunge and am building a Linux lab server around a E2100 Xeon. I have six 8TB SATA drives that I plan to put into a ZFS RaidZ2 pool. I am considering adding some L2ARC and ZIL/SLOG cache to increase IOPS and I have a 240GB M2 SSD (Corsair MP510) for that. To complete the...

    Hi All, in ZFS is there any way to calculate snapshot sizes per file, the "per file" is the important part here lets say i have ZFS pool that have 10 vm images (vm image is just a big file from ZFS perspective) and i am snapshoting the whole pool once per day now lets say we have 10 snapshots...

    Intel M10 as Zlog in low end file server

    Hi I am looking to upgrade my file server a bit. It now has a E3-1200v2. I am looking to upgrade to a Ryzen 5 3600 or Ryzen 7 3700X. I would like to use sync=always to improve data consistency. Most if not all access is using NFS anyhow. On the motherboard I am looking at (Asrock Rack X470D4U)...

    How to monitor/identify used blocksize (for different data)
