The licensing and resulting encryption-performance (first time hearing about that TBH) situations are indeed unfortunate. The one point that that I feel is bordering on bad faith is complaining about the pitfalls of deduplication. Basically everyone (including official docs) will tell you not to use it unless you’re an expert with very specific reasons. It’s not functionality present in any other filesystem I know of and OP then agrees that it’s not a needed or even desirable feature anyway. It’s basically just present for backwards-compatibility at this point. > No disk checking tool I don’t understand this complaint. Is this not what you get by running scrub with checksumming enabled? > High memory requirements for ARC This section is simply wrong or at least very misleading: the main motivation for ARC today is not that ZFS can’t use the page cache but that its own strategy can perform better and more optimally (if tuned properly). Things generally do not get double-cached in both page cache and ARC at all. The memory usage can be tuned with various parameters including min and max sizes (though I do wish these parameters could be set per pool as opposed to on a system level). This section too seems to be in bad faith as a reader who is not deeply familiar with ZFS already will have an incorrect understanding. > causing long periods of unavailability until a workaround can be found. Has it really? The one situation I’m aware of is the one they’re mentioning. Which was not experienced any differently than the usual expected delay for things to bubble down to distro repos. > btrfs Is simply not ready for casual users yet. It will hopefully get there before too long but at this point I find it irresponsible to recommend it for non-expert users and production workloads. OpenZFS is not perfect and there are valid reasons not to use it. You don’t have to misrepresent it to find them.
