ZFS

“the challenge was the boot sequence required for a custom kernel and rootfs was pretty non-transparent”

“The contents, whether old and stale or brand new, can (and should) be read routinely and checksummed to confirm integrity”

“The storage system is still alive, still available for reading and writing, and still redundant for that entire time.”

“my favourite FS can't be "randomly removed from the kernel unexpectedly after some OS update" because it never made it in — ZFS.”

“I've tested my own machines running ZFS by random writes out of band from the filesystem/kernel and it has always found and fixed them.”

“either use the product's own snapshot functionality (ZFS has those), or switch to the product that does”

“Given the license issue with zfs - and in particular, the technical fallout like needing dkms”

“As someone who originally ran it on Solaris when it came out ~20 years ago, and have continued to run it on FreeBSD and Linux”

“They're automatically snapshotted with ZFS to help prevent my own errors from deleting or corrupting stuff accidentally.”

“there are plenty of useful things to be done with zfs dedupe at practically no cost if you design for it ahead of time”

“encrypted ZFS was not considered production due to obscure file corruption bugs that were unpatched”

“Has worked well and a big plus is being able to tell the agent to just solve it's mistake via restore from the snapdir.”

“Run ZFS backed filestore on FreeBSD, have migrated it to/from Debian. Over 15 years, on over 50 hosts/NAS/SAN instances”

“ZFS was the natural choice, again snapshots, boot environments, native encryption and just maturity/reliability”

“ZFS offering to fix it was massive selling point and the time and based on personal experience, it delivered.”

“I can't count the amount of times i have wiped or edited something by mistake and then restored it within seconds with it.”

“ZFS for media production allows studios to optimize storage for each department, improving performance across animation, compositing, editorial, and databases”

“I'm extra fond of ZFS backed network root filesystem, because it lets you put an OS on ZFS without needing to deal with ZFS support in that OS.”

“ZFS incremental replication on top of regular app backups provide a quick recovery process should the hardware of that machine fail.”

“I had ZoL ZFS troubles that the maintainers shrugged off requiring transferring everything to another volume”

“ZFS is out because the Linux developers refuse to cooperate by providing the hooks it would need to avoid duplicating the disk cache.”

“With some extra NVMe/Optane allocated to regular ZFS read cache, and all my spinning-rust data VDEVs also as RAID10”

“Having each boot environment available as a ZFS snapshot capable of being managed the same way as any other dataset, capable of being sent and received, is such a powerful feature.”

“I don't know that I can recommend arch+zfs to someone not familiar with arch linux though.”

“I've run ZFS on almost all my machines for years, some with only 512MiB of RAM. It's always been rock-solid.”

“ZFS really works fine with very little RAM (even less than the recommended 2GB), just with a smaller cache and thus lower performance.”

“Creating snapshots and sending them is efficient enough to use it as the underlying storage for moderately loaded databases and VMs.”

“whenever I've tried to learn more or troubleshoot an issue like the performance degradation I'm experiencing now, I'm met with confusing viewpoints and documentation”

“With modern filesystems like zfs or btrfs, you can take a full snapshot every minute and keep it for a while”

“ZFS is for managing your data with simplicity and efficiency that isn't possible with other "storage systems" on GNU/Linux.”

“People may argue that zfs of xfs or jfs or ffs is better than ext4, but are they gunna jump in and fix it for free”

“there have been a number of bugs where ZFS panics because the spacemaps say something insane”

“very old versions of ZFS appear to have quietly written slightly incorrect ACL information”

“Linux on ZFS that is automatically snapshotted every minute might be (part of) a solution to this dilemma.”

“ZFS did a bunch of stuff right, it's just a much older design; pre-extents, and based on the original Unix filesystem design”

“ZFS does double caching and doesn't have a way to consolidate extents except to rebuild the FS.”

“if anything, having a copy-on-write filesystem like ZFS on your firewall/router means you have better integrity”

“in that time I've always able to wrest the system back into order even on the seemingly most-unlikely, least-resilient, garbage-tier hardware”

“We used it at $job for zfs file servers because it's native and much more mature than linux alternatives.”

“if you are using ZFS RAID Z2 you can use literal used garbage hard drives safely without risking data loss”
