    R820 / H310 "Adapter at Baseport is not responding"

    I posted this on Dell's community as well but no responses as yet. So I think I have a serious problem that I need any help I can get. I don't know if the H310, the SAS cables, the enclosure, or the drives are bad. I will explain. I purchased a re-purposed R820 with an H310 and 10 1TB...

    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...

    Sanity Check

    Retooling my backup solution to have more space and failover potential. I have 2 1U servers left over from an older project both identical with 4 3.5" bays. I am wanting to have a somewhat large network backup target. Mainly for accessible archived storage for potential later use. I have a few...

    Getting the ZFS file size including all its snapshots

    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)

    Hi, I decided to split up my large FreeNas pool into smaller ones. While doing that I want to optimize (recordsize of) the new pools for the different content that I have (video, photo, documents, software, vms). While that is fairly simple for videos i struggled for photos. Historically I...

    ZFS insufficient replicas on replaced disk

    Hi. I hope someone here can help me. Since 2015 I have z pool of 5 WD reds in raidz2 on Ubuntu server 16.04 and recently one of my drives started reporting checksum errors. After scrub error count went up and I decided to check if I should replace the drive. Smartctl said what SMART reports...

    Relationship between Cache, Storage Density, Rotational Speed and PMR / SMR

    Seems the SMR drives have inflated cache to compensate for lower performance. The SMR drives however have really appealing densities and form factors (4tb in a 2.5” package, that’d be 96tb in a 2U 24 bay Supermicro chassis). So, first question: are they really so bad? I’m guessing the response...

    Two Intel Expanders, Same Chassis. ( RES2CV240 + RES2CV360 )

    I have a 4U chassis which I can fit 36 2.5" (4x 8 + 1x4). I'll be using SATA drives, but may migrate to SAS. I'll be using ZFS to manage the array. So, the 1x4 will house the SSDs and hot spares I presently have an Intel RES2CV360 and RES2CV240 which are laid out like this: From what I...

    Intel NUC single SSD - best filesystem for Proxmox

    Just picked up an Intel Coffee Lake NUC. I've ordered a single M.2 NVMe SSD (1TB Samsung 970 Evo Plus). Wanted to run a few test VMs at home on it, nothing critical. Would ZFS be the best filesystem to use or would XFS/ext4 be better?
