What can ZSys, our dedicated helper for #ZFS systems, do for you and how can you interact with it? Discover here what's new with 20.04 LTS for ZFS compared to 19.10 in terms of installation and general features.
My interest in Sedna PCIe adapters for SSDs has overspilled into obsession ๐ฅฐ with the arrival of 2x quad SSD cards today, one for SATA and one for M.2 SATA ๐ฎ I blame the arrival of #ZFS on #Ubuntu Desktop ๐ช #WimpysWorldhttps://wimpysworld.io/33lYn5d
@xanderio@raichoo There is an awesome presentation by Allan Jude from this year's #FOSDEM: #ZFS Powered Magic Upgrades: Using boot environments for atomic in-place upgrades
@moonman Thatโs heresy. (I havenโt used either, so it is all hearsay, but everything Iโve heard says that #ZFS is superior in every way to #BTRFS.
Cross-DSO CFI will definitely not make it for #HardenedBSD 12-STABLE. There's still a lot to work out, especially with regards to package builds.
The reason why Cross-DSO CFI works with 90% of installed software on my laptop is because they were pre-installed from before installing Cross-DSO CFI (thank you, #ZFS boot environments).
By the way, #zfs on #linux merged a rather nice feature earlier: Metadata Allocation Classes, which allows the user to have vdevs that are marked specifically for e.g metadata, dedup information or small blocks. It's been in development for quite a while and will end up in the next release (0.8.0.). Link to the PR: https://github.com/zfsonlinux/zfs/pull/5182
What's the fastest you've ever spun up a brand spanking new container? With #FreeBSD jails + #OpenZFS#ZFS, I got the time down to 0.27 seconds (with debugging code enabled).
#FreeBSD recently introduced a utility in base, bectl(8), to manage #ZFS Boot Environments. It can mount the BE as a jail, so you can do nifty things like:
ZFS help needed. I powered-up a server that was dormant for months. Fresh install of #KDE (Kubuntu 18.04). I had a #ZFS RAID-Z pool configured on the previous installation (Ubuntu 16.04) but didn't export the config. Now I'm wondering how I should re-configure the pool preserving the data. Here is output from "sudo blkid | grep zfs" in a pastebin - https://pastebin.ubuntu.com/p/K4WQhcjndG/
