btrfs or ext4
by François Patte 02 Jan '21

02 Jan '21

Bonjour, I try to build a home nas to make a dlna server for audio, video and pictures. I have 2 disks for the data which I want to be mounted in raid1 (software). I formated the two disks using btrfs (mkfs.btrfs -m raid1 -d raid1 /dev/sda /dev/sdb) It works but, up to now, I can't see the advantages of this file system vs ext4 managed by mdadm. One disadvantage is that it seems that monitoring the system is not possible in case of disk failure for instance. Illuminate me with your knowledge. Thank you. -- François Patte UFR de mathématiques et informatique Laboratoire CNRS MAP5, UMR 8145 Université Paris Descartes 45, rue des Saints Pères F-75270 Paris Cedex 06 Tél. +33 (0)6 7892 5822 http://www.math-info.univ-paris5.fr/~patte FSF https://www.fsf.org/blogs/community/presenting-shoetool-happy-holidays-from…

systemd automount
by François Patte 02 Jan '21

02 Jan '21

Bonjour, I configured an automount of directories located on a server on my local network: in the fstab of a computer on the network I put the line: 192.168.1.16:/data /home/patte/data nfs noauto,rw,user,nofail,x-systemd.automount,x-systemd.mount-timeout=30 0 0 It works. If the server is down, no problem, the boot of the computer is OK. But if the server gets down while the computer is working, this turns in an awful way: everything on the computer becomes very slow, opening a file manager takes ages, the ls command does no work and it is impossible to unmount the directory on which the server is mounted. Did I forgot an option in the fstab? Is there a way to solve this problem without shuting down the computer (which also takes ages...). Thank you for helping. -- François Patte UFR de mathématiques et informatique Laboratoire CNRS MAP5, UMR 8145 Université Paris Descartes 45, rue des Saints Pères F-75270 Paris Cedex 06 Tél. +33 (0)6 7892 5822 http://www.math-info.univ-paris5.fr/~patte FSF https://www.fsf.org/blogs/community/presenting-shoetool-happy-holidays-from…

kdenlive not supporting internal laptop camera?
by Neal Becker 01 Jan '21

01 Jan '21

I need to record a video using my laptop builtin camera. The camera works fine in other apps. I tried kdenlive installed from rpmfusion, but there doesn't seem to be any choice for the camera input. Settings/configure kdenlive/capture only has tabs for: screencapture, blackmagic, and audio. When I search the web it seems I should have a tab for ffmpeg, but it's not there. It does appear from help/about that kdenlive was built with ffmpeg. Any ideas? Thanks, Neal -- *Those who don't understand recursion are doomed to repeat it*

many F33 deltarpm rebuilds failing with md5 mismatch error
by Andre Robatino 01 Jan '21

01 Jan '21

In the last few days, I've noticed that F33 deltarpm rebuilds often fail with an md5 mismatch error. This would happen occasionally before but happens almost all the time now. Has this been reported? I don't see anything in bugzilla.

automount requests
by Greg Woods 01 Jan '21

01 Jan '21

My logwatch each day has dozens of messages like this: pub.automount: Got automount request for /pub, triggered by 242640 (PT3122): 1 Time(s) I want to determine why this is happening, because the drive containing /pub (on a different machine mounted via NFS) is spun down when idle, and these events are likely causing it to spin up. My understanding is that the part inside the parentheses is the command name of the process that triggered it, but I don't know what the "PT" syntax means. Thanks for any info, --Greg
