00:01:46 VVD: resilvering completed OK - mirror-vdev online no errors 00:01:59 thanks VVD and mzar 00:04:32 👍🏻 00:38:23 can zfs on geli do trim on a ssd? 01:25:12 how can i access a jail via serial console? i know jexec, but i'd like to have some uniform method for VMs and jails... 01:33:00 hi 01:33:12 How do I get the exit code of a subshell invocation? - $? gave an error of non-portability for /bin/sh 04:35:03 how do i setup zfs on geli to do trim on a ssd? 04:35:13 https://web.archive.org/web/20180217042350/http://blog.branix.net/freebsd-hints/en 04:37:57 is it automatic? 04:42:24 nomia: i didn't really trim. what do you mean? 04:43:12 nomia: i don't remember any of these when i have geli in my ssd 04:46:01 except the partition 05:16:25 i mean ssd needs trim right? 05:16:44 so geli has to support trim from zfs 05:18:27 luke_jobless_sb: does your zpool trim work? 05:19:06 nomia: Read geli(8) 05:23:48 you FreeBSD folks and all your fancy zfs talk 05:53:15 SponiX: do you notice when someone refers to certain manual 06:55:10 SponiX: heresy against ZFS will not be tolerated :p 06:57:00 the website discussion area list is incomplete: doesn't list the oldest one 08:02:03 hi folks. I built a structure for jails that uses a read-only base system and mounts writable paths on top of it. I'm confused as to why some symlinks are wrongly followed. Here's the symptom: 08:03:03 I have /etc -> /skeleton/etc . Then I have the usual /skeleton/etc/ssl/certs/ which contains symlinks like b66938e9.0 -> ../../../usr/share/certs/trusted/Secure_Global_CA.pem . What confuses me is the following: 08:04:31 this setup was working fine in FreeBSD 13. However in FreeBSD 14.2 those symlinks fail to resolve. Files /usr/share/certs etc exist. But when I "cd /etc/ssl/certs" and try to access them from there, I get "b66938e9.0: No such file or directory" 08:05:52 If instead I build a symlink to the absolute path, then the symlink works. What am I getting wrong here? 10:59:35 as soon as it snows here the city gets blocked local gov never cares cleaning roads in city 12:18:30 Yeah I trim daily through crontab 12:18:53 It's supposed to do it automatically but still the daily job runs for 20 mins so it must still leave a lot to be desired 12:19:27 And this is fine anyway because then I can do it while I sleep 12:20:20 Here's a question that's been bothering me for a while: Can I run freebsd-update on 50 jails at the same time? I've been doing them one by one all night. I'm done with 15, I have ~20 more. 14:19:06 l @antranigv I feel like you would have bandwidth contention issues doing them all at once. Maybe set up a script that does them one by one for you? 14:19:19 @antranigv 14:38:44 My user is in video group. Nvidia- driver loaded. Wjen i try to startx i get .Xauthority does not exist... 14:39:38 I did everything following handbook 14:43:31 I have try touch .xauthority, errors gone but connection to x server lost. I have try deleta and make new user. I have try complete bsd reinsrall. - always the same error 14:51:19 Its bad package... i did everything i could. I have even try build xorg from ports, bit it pulls mesa, llvm, clang.... nvidia-driver doesnt need any of that 14:53:24 I dont know what to do anymore. Im dealing with this problem for 2 days 14:53:28 Any help ? 15:10:51 Guest39: i haven't used freebsd on the desktop with nvidia recently, but 8 years ago or so, there was an nvidia-xconfig or something along those lines that would generate the configuration for you. also, are you using the modesetting driver or just nvidia.ko? 15:44:56 nvidia-xconfig is still a thing, installed by package nvidia-xconfig-525.116.04 15:45:43 @Guest39 have you tried following the FreeBSD Handbook? It is very good. 19:04:22 Howdy, folks! 19:06:28 vfs.zfs.arc_max if i have 0 on this value in sysctl, can zfs use the amount of memory it wants then ? 19:32:08 n30: yes 19:42:14 mzar: thanks 19:42:50 if i do a dd if thenn of to create a large file ... like 1G and then do du -sh file and it says 512B only ? 19:42:56 why does it do like that 19:43:38 it's compressed 19:44:15 hmm do i want to use that ? or i gain more performance without compression ? 19:44:55 probably yes 19:45:12 more performance with compression 19:45:35 but i cant verify how big files are then ? 19:48:07 use du -A 19:48:22 or ls -l 19:49:59 ahh thanks 19:50:33 i see this in top: ARC: 5888M <-- is that how much ram zfs using right now ? 19:52:06 yes, it's the cache 19:52:19 Adaptive Replacement Cache 19:52:43 then i know :D thanks for the answers and help :D 19:53:11 i have never used zfs before, did reinstall my server with zfs today due to slow disk speeds without it even if i use ssd drives 19:53:12 n30: you can learn about it here https://papers.freebsd.org/2019/FOSDEM/jude-eli5_zfs_caching.files/ELI5_ZFS_ARC.pdf 19:55:21 ZFS is more than filesystem, good luck with learning 19:56:09 yeah i know that little about it... have thought a long time about try it out but i have never gave it the chance... but today i thought its the last chance for this server or i will replace it 19:56:18 but it seems to work pretty nice now 19:57:11 it's on ssd, so you probably want to enable autotrim 19:58:29 yes i have ssd drives but there is some crap with the p410 raid controller the cache battery is dead so the performance is extreme slow without zfs. i did write 1G file on 80 seconds 19:59:07 but when i wrote that file the server almost stalled ... so i broke my raid 1 and setup the drives as raid 0 and striped them with zfs 20:00:47 OK, but some people say that HBA mode is even better than JBOD 20:01:12 yes but this p410 card do not seem to have HBA mode 20:01:36 p410 ? is it HP ciss(4) ? 20:01:57 yes 20:02:08 in hp bl460c g7 blade 20:02:50 they work fine in JBOD mode, HBA is not avaliable 20:03:13 cannot trim: no devices in pool support trim operations 20:03:24 did i get when i tried to enable trim with zpool trim zroot 20:03:37 yes, it won't work with ciss(4) 20:07:53 the controller doesn't expose drive to OS 20:08:36 nah that is true 20:36:41 mzar: did make new world and recompile kernel and install new kernel then reboot ... will it empty arc before rebooting normally or what? it 4-5 minutes then i rebooted my server now and its not online yet 20:44:23 if it's not back yet than probably something went wrong, but ARC has nothing to do with it 20:44:51 you can set serial console over lan 20:45:37 i have ilo so i will check it out im just waiting for access to computer so i can access the ilo on the server to see what happend 20:46:35 nice, but setting serial console is even better since ilo requires java IIRC 20:48:47 n30: do you boot it from BIOS or EFI ? 20:49:16 that i need to check ... i think its from bios 20:50:39 OK, if you will seek how to configure SoL (OS part) poke me 20:51:48 I have it working on old HP DL 360 and it won't break iLO 20:52:56 now im not sure if i follow/understand ? do that have with zfs to get it to boot if it have failed in somehow ? 20:54:33 SoL has nothing to do with ZFS, it's IPMI feature 20:59:18 it was me forgot to add the module for nic in kernel :d 20:59:54 you can load it later 21:00:01 or with the kernel 21:07:20 i loaded it in kernel i forgot it before only
