ZFS can use any blockdevice it can see, does not matter if it is a disk, a partition, a file, a iSCSI target or a hardware raid. With the last you should know that you need a driver for the hardware raid card. As this is not common on ZFS, driver support can be limited ex on Unix or drivers not...

https://omnios.org/releasenotes.html Unlike Oracle Solaris with native ZFS, OmniOS stable is compatible with Open-ZFS but with its own dedicated software repositories per stable/lts release. This means that a simple 'pkg update' gives the newest state of the installed OmniOS release and not a...

Be aware With enough RAM, L2Arc only helps when you reboot quite often and you have many users with many volatile files For a pure filer, sync write is not needed and only lowers write performance without gain. A special vdev is not a cache but the only place where this data is stored. Unlike...

I can agree that USB is not as reliable as Sata or SAS, mainly due driver and controller problems with some of them, so USB disks for a regular fileserver instead Sata/SAS is nonsense. But I have not seen statistics to condemn them in general for any use case. USB is the primary option for...

There are three questions about this: - Does this affects ZFS more or less than any other filesystem (is it more secure to use ZFS than other options with USB) - Does the controller commits a write when data is not on disk (this is the real question and such data caching should not happen even...

If a USB firmware does write data to disk "on its own" it is buggy, nothing to do with ZFS. In any other cases, a sudden disconnect is uncritical, on other filesystems a single sudden disconnect is critical often on first occurance. There is only one case that ZFS cannot control, this is a...

There is no fschk or chkdsk on ZFS because you do not need and there is nothing that can be fixed by such a tool. A sudden crash or disconnect on ext/fat/ntfs can result in incomplete atomic writes with a damaged filesystem as result. Fschk or chkdsk are there to repair filesystem problems as...

If you plug in two disks with ZFS pools and same name on them and call zpool import, you may not be able to import based on name but only based on unique uid and a different name on second import. No other problems to be expected. A unplug without prior export may be a bigger problem as this...

New snapshot Openindiana 2024.04 is out (successor/fork of OpenSolaris) https://www.openindiana.org/announcements/openindiana-hipster-2024-04-announcement/

If Proxmox fits your expectations (I miss the easyness and ntfs alike ACL of the Illumos/Solaris SMB server vs SAMBA), you can combine napp-it cs for ZFS management (beta) with the Proxmox gui for VM management. (Open Proxmox in a tab beside napp-it)

All in One MK II Around 15 years ago, I came up with the All in One Idea (VM Server with a virtualized ZFS storage server). From the ....NAS forum, I got remarks that this is stupid and cannot work. Now AiO configurations are quite common...

I increasingly have the impression that Proxmox is becoming THE Linux universal server Current, very well maintained kernel with Debian as basis very good virtualization capabilities well-maintained ZFS This paves the way for Proxmox as a universal Linux server not only for any services as a...

I have it included it now this way to behave like on Free-BSD or Proxmox You can share a filesysystem with guestok. If you activate "enable guest account" an anonymous user entry is added and the kernelbased SMB in GZ enabled. Local usermanagement is currently not intended as adduser and...

New release of ZFS on Windows zfs-2.2.3rc4, it is fairly close to upstream OpenZFS-2.2.3 with draid and Raid-Z expansion https://github.com/openzfsonwindows/openzfs/releases/tag/zfswin-2.2.3rc4 rc4: Unload BSOD, cpuid clobbers rbx Most of the time this is not noticeable, but in...

You can use any tool as intended or you can use it for a different problem that may require some modifications I see three limits regarding SmartOS 1. every modification must happen under user control ex via an option in the sharing dialog "enable guest user" to allow SMB access (this is what...
