01:34:23 Thanks all 11:31:08 my cmake at fbsd 13 has not found the yaml-cpp, but I am sure it has been installed. Can you help wha am I missing? 11:31:24 yaml-cpp not found (re-run dependencies script to install) 11:41:56 FreeBSD 13.1, ZFS on root, and I sized the swap partition too short when installing. (Meant to have swap = RAM, but left it at 2GB and didn't notice until now.) No free space on disk for other swap partitions. Shrinking a zpool doesn't look possible. Am I correct that my only option is zfs send + zfs receive to a removable disk, recreate the swap and data partitions, and restore? 11:59:21 Do you feel comfortable with swap on ZFS? 12:06:01 I'm not sure swap on ZFS is a good solution for anyone, unless they're very comfortable with not just the VM subsystem but also having to spend (up-to) several weeks tweaking the VM watermarks for various reallife system loads (which can't be realistically generated through benchmarking) 12:07:34 yeah. 12:07:39 And given that the results of the catch-22 is a system that'll be completely locked up (unlike a lot of other OOM situations, which FreeBSD can recover), it's not exactly a fun time. 12:07:55 seen that a lot on illumos. 12:08:00 also, uh. 12:08:07 should I rewrite my mail system in lua? 12:08:33 Seems like that's a decision you should make. 12:08:52 V_PauAmma_V: as for shrinking ZFS, yes the only option is zfs send | receive. 12:13:25 you can remove vdev if it is not raidz 12:14:05 V_PauAmma_V can correct me if I'm wrong, but I'm fairly sure this is a laptop with a single disk. 12:14:30 Reinhilde: Exactly how are you thinking of putting swap on ZFS? Point to a ZFS-backed file in the mntopts column? 12:15:22 no ghoti. using a zvol. That's how it's done on illumos (where I've had my problems with swap-related lockups). 12:15:42 There are a few options for it, some worse than others. :) 12:15:48 Unless you're absolutely sure your filesystem, disk drivers, and anything else in the swap datapath has 0 bugs, it's always best to use character devices for swap, rather than files. 12:16:34 By using zvols, you at least avoid the ZFS POSIX Layer 12:17:24 Reinhilde what kind of lockups? 12:17:35 Ya.. If the ideal is to use no ZFS at all, at least zvols are closer to that than a file. 12:18:11 tsoome_, I don't fully remember. I've not had one in a while. 12:19:36 just curious - since solaris 10 got zfs root, every single setup I have done has swap zvol (including illumos), and never seen problem about it:D 12:20:59 (does not mean that there is no chance for some bug) 12:22:37 debdrup: I'd love your thoughts on this.. I have an exfat portable usb ssd. I want permissions and such. Planning to use it for nearline backups of ZFS datasets. Should I reformat it as ZFS? Or go with UFS2? (Perhaps it does not matter, as both are "not exfat" which is my priority.) 12:37:07 And I'd love it if people don't expect me in particular to answer their questions, but we can't have everything now can we. 12:38:40 tsoome_: it's not so much a bug as it's a question of what happens when the system is low on memory, tries to swap, which will change ARC pressure which in turn means it has to free some memory, which means it tries to swap and ends in a catch-22. 12:39:01 So it depends heavily on VM watermarks, which on FreeBSD are usually set to use basically as much memory is available. 12:39:26 This is partially due to the unified memory buffer in FreeBSD, but also because free memory is wasted memory. 12:44:09 well, ye, thats why I like the paging approach in sunos - with paging you get early warning long before the system starts to swap. 14:44:40 So Stable gives me a tzx checksum error release kernel panics and the other one kernel panics. Will my card eve really be supported AX201 15:05:09 * V_PauAmma_V nods thanks at debdrup. (And to confirm: yes, laptop with single disk.) 18:08:14 debdrup: sorry about asking you directly; you were already in a zfs discussuion in the channel, so I thought the timing as apropos as an add-on to that. 18:10:04 * axis9 visualize self in zfs support chann el 18:51:43 which one? I know two :) 23:42:38 koobs: Current/Stable/release all failed stable was a checksum error and the other two kernel panicked cause of my WiFi driver. It's fine I will install freebsd when they get everything ironed out 23:45:44 jb12779761, stable is just another dev branch 23:57:33 https://wiki.freebsd.org/WiFi/Iwlwifi/Chipsets 23:57:34 Title: WiFi/Iwlwifi/Chipsets - FreeBSD Wiki 23:59:14 cpet: Got it
