    Culprit: slightly bad LSI card - was: SC847 45-bay JBODs rear backplane issues - anyone else?

    Edit / Conclusion: These errors were intermittently being logged against drives in a SAS expander JBOD for writes only due to a mostly good, but partly bad port on an LSI SAS9206-16e card running IT mode P20.00.07 firmware: mpt2sas_cm1: log_info(0x31120303): originator(PL), code(0x12)...

    LSI 9270-8i IT mode

    Sorry if this has already been answered elsewhere. I did a forum search but couldn't find exactly what I was looking for. I have a client with an LSI 9270-8i, with 8 drives currently connected. No RAID, just pass-thru to the OS (currently Server 2012 R2). This works fine for their current...

    ZFS, possible to limit/control ARC size per pool ?

    Hello, i wonder if there is a way to have more fine grained control about ARC usage than limiting arc for the whole kernel module, and therefore all pools. Let's say i have three pools, one for the root-filesystem, the other for data and one for backup. I want the root-pool to consume a fairly...

    Home server architecture thoughts?

    In this thread, I posted pics of my recently-rebuilt home server. Now that the hardware part is done (maybe?), I'm thinking it's time to revisit the OS/software side. So I'm soliciting feedback. I don't think anything is really broken, but mostly non-optimal due to having grown up...

    I want to build One Computer To Rule Them All. I plan to have a multiheaded setup, with one pair of monitors, keyboard + mouse each Windows and Linux, running in VMs. Windows will be used for gaming and graphic art projects, Linux for data science/bioinformatics, so performance is important.

    How to replace failed ZFS mirror rpool drive?

    I had a Proxmox host using 2x 2.5" 1TB HDDs lying around as boot drives. I selected zfs rpool and it worked great for the past year. Then, /dev/sdb died. It's not even on the controller? I had remote hands move another 1TB drive from a random storage array into the slot. So I've now got a...

    Linux based FreeNAS alternatives

    Poking around the internet looking for a NAS Distro to try. I was planning on going to FreeNAS Corral since it had Docker Integration...but we know how that went :( Seems like most people have gone to ZFS historically because it was more stable than BTRFS, but is that still the case today...

    ZFS volumes used by iSCSI showing double space usage in zfs list?

    Hi all I just started testing iSCSI volumes from my Solaris 11.3 server to my Windows 10 workstation. It's working great, and was super easy to setup. But I am seeing one very confusing thing: zfs list always reports far more data used in the ZFS volume than I have actually created. I...

    ZFS: Partitioning drives = write cache disabled?

    Hi all I'm hoping to get a high-performance PCI-E SSD to add to my home Solaris 11.3 file server/NAS. Specifically, a 1.2TB LSI Nytro Warp drive. (Forum thread here.) This device is an LSI 2308 with 6 x 200GB SSDs, which by default are configured as a hardware RAID-0. But I believe it is...

    ZFS read caching with SSD: is cache used as well as storage, or instead?

    Hi all I am upgrading my Solaris 11.3 home server/NAS. I have 27 x 2TB SATA3 drives, which will be configured as three 9-drive VDEVs; either 3 x RAIDZ2 or 3 x RAIDZ3, I haven't decided yet. I also plan to add a couple of SSDs for SLOG and read cache, and my question for this thread is about...

    Diskless Windows 10 workstation booted from NAS - possible? iSCSI? SMB?

    Hi all I'm in the process of a major upgrade to my home NAS. The server runs Solaris 11.3, with hardware of: 2 x 2.93GHz hex-core LGA1366 CPUs, 72GB RAM (considering upgrading to 120GB) and 32 ports of LSI 6GB SAS/SATA (2 x 2008, 2 x 2308). I currently have 27 x 2TB 7.2k SATA drives...

    Do you guys spindown disks in zfs pools?

    I have a setup with a few SAS drives for home NAS running on an intel server with openmediavault. ( Debian 7 ish). But I cant for the life of me get them to spin down. I would like it for power saving. At least half of the day. I guess one of the issues is that hdparm doesnt want to talk to my...

    smartmontools / smartcli causing software errors on disks whenever used?

    Hi all I recently started using smartmontools, installed via the CSWsmartmontools package on my Solaris 11.3 server. I am particularly interested in this for temperature measuring of my 24 HDDs - in particular the 12 that are in my external JBOD chassis, which doesn't have much airflow between...

    Proxmox ZFS pools under mergerFS, I wonder if anyone done that before ?

    as the subj. says, can it be done and how? I have been planning to rebuild my home server with Proxmox VE 4.4 but as I have a single server, hardware wise, I need it to be a VM server AND a file server. reading up on ZFS lead me to conclusion that while it is a nice robust FS it has it's...

    SAS2308 vs 2008 - any big value in upgrading, besides PCIE b/w?

    Here's my question in a nutshell: what are the benefits, if any, in upgrading SAS2008 cards to SAS2308 cards, besides offering PCIE 3.0 bandwidth and being capable of handling more devices (1024 vs 512)? If you had a server that only supported PCIE 2.0, containing several SAS2008 cards running...

    Moving from Solaris 11.3 to OmniOS (or OpenIndiana): anything important to know?

    Hi all I am currently running Solaris 11.3 on my home server. I went with Solaris 11 because I was a Solaris 10 + OpenSolaris admin for many years, so it is what I know. Plus I have a free license for Solaris 11, so licensing/patches are not a concern for me. But now I am thinking I made a...
