Hey, Just tried to mount a btrfs 0.19 in a image file: dd if=/dev/zero of=btrfs-play.img bs=1024k count=256 losetup -f btrfs-play.img losetup -a /dev/loop0: [fd02]:24653 (btrfs-play.img) mkfs.btrfs -L BTRFStest /dev/loop0 WARNING! - Btrfs Btrfs v0.19 IS EXPERIMENTAL WARNING! - see http://btrfs.wiki.kernel.org before using fs created label BTRFStest on /dev/loop0 nodesize 4096 leafsize 4096 sectorsize 4096 size 256.00MB Btrfs Btrfs v0.19 btrfsctl -A /dev/loop0 operation complete Btrfs Btrfs v0.19 mount -t btrfs /dev/loop0 btrfs-test/ mount: tipo fs errato, opzione non valida, superblocco su /dev/loop0 danneggiato, codepage o programma ausiliario mancante, o altro errore In alcuni casi si possono trovare informazioni utili in syslog. Provare ad esempio 'dmesg | tail' dmesg | tail [140443.202115] device label BTRFS_mypole devid 1 transid 7 /dev/loop0 [140443.202369] BTRFS: couldn't mount because of unsupported optional features (1). [140443.202480] btrfs: open_ctree failed Did I miss something? Using ext3/4 the above works flawlessly.. Probably it's only due to the "open_ctree" problem above. Using kernel 2.6.30 and btrfs-tools 19-2 (debian). Any hints? Thanks. -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
