I've been using ReiserFS quite happily for many years now and I think it is one of those software packages that was an excellent/genius design; it has needed very little maintenance over the years. The PowerThatBe, however, think that it is 'unsupported' (actually it isn't, it just doesn't have the crowds that theext4 does since it don't need much work, which to my mind reflects badly on ext4) and so are depreciating it, especially with Leap-15. ReiserFS does have the problem that it is single threaded, so I don't get the best performance when I have so many file system running it :-( I don't see reiser4 being merged in in teh foreseeable future. So I'm looking to migrate to another obscure file system. JFS. I've used JFS extensively for many years (hmm over a decade) on IBM AIX machines. (Where I always used it on top of LVM.) Like ReiserFS and XFS and BtrFS it beaks away from the archaic model that goes back to the pre-networking UNIX V6 days on the PDP-11 where the inode space and the data space blocks were preallocated and fixed at MKFS time. This idiocy is preserved even with ext4FS! All these late model file systems are based on B-tree models so there is no reason why ext4FS should have this constraint. My one question is about concurrency. In some ways it a dumb question. The Linux implementation of JFS was done by IBM engineers so presumably it reflects the way the IBM AIX implementation worked, but I can't find an explicit answer in the extensive AIX documentation I have either. Is JFS multi-threaded? Please: no answers that are "Not invented here" & other prejudices. Particularly Ext4, BtrFS and XFS. "Comparisons are odious". I'm also not interested in building my own kernel https://reiser4.wiki.kernel.org/index.php/Reiser4_Howto And please, this is a desktop, not a file server, so advantages such as dealing with 16Tb files or file systems are of little importance, but the handling of lots of smaller files (such as ReiserFS does very well) *IS* important. That is why I'm asking about multi-threading. That's the ReiserFS limitation for me. ==================== -- A: Yes. > Q: Are you sure? >> A: Because it reverses the logical flow of conversation. >>> Q: Why is top posting frowned upon? -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
