Re: syslog message repeated 3x
Hi, I just try your steps, but only 1x log message. Anyway, i use the latest btrfs-progs. git://git.kernel.org/pub/scm/linux/kernel/git/mason/btrfs-progs.git Can you try this and see if it happens again? Thanks, Wang I'm just curious why the last of the following 3 commands : $ dd if=/dev/zero of=/mnt/ramdisk/disk1 bs=1M count=257 $ yes | /sbin/mkfs.btrfs /mnt/ramdisk/disk1 $ mount -o loop /mnt/ramdisk/disk1 /mnt/t gives 3x the same log message : 2013-05-09T11:23:00.230+02:00 n22 kernel: device fsid 5b4be7c4-e662-459a-a2a7-066e9384c901 devid 1 transid 4 /dev/loop1 2013-05-09T11:23:00.581+02:00 n22 kernel: device fsid 5b4be7c4-e662-459a-a2a7-066e9384c901 devid 1 transid 4 /dev/loop1 2013-05-09T11:23:00.583+02:00 n22 kernel: device fsid 5b4be7c4-e662-459a-a2a7-066e9384c901 devid 1 transid 4 /dev/loop1 -- MfG/Sincerely Toralf Förster pgp finger print: 7B1A 07F4 EC82 0F90 D4C2 8936 872A E508 7DB6 9DA3 -- To unsubscribe from this list: send the line unsubscribe linux-btrfs in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html -- To unsubscribe from this list: send the line unsubscribe linux-btrfs in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
Re: syslog message repeated 3x
Oh, My kernel version is btrfs-next. This message gets from kernel..so you can try this url: git://git.kernel.org/pub/scm/linux/kernel/git/josef/btrfs-next.git Hi, I just try your steps, but only 1x log message.

The message is informational and doesn't indicate any kind of issue with the FS. I'd just ignore it/them. (Also, are you running btrfs dev scan beforehand or not? It'd be interesting to see the difference in your logs -- particularly with timestamps -- when you do that.)
