(please ignore my previous email, because I wrote somewhere "top id" instead of "top level") Hi All,
I am trying to figure out which means "top level" in the output of "btrfs sub list" ghigo@venice:~$ sudo btrfs sub list / [sudo] password for ghigo: ID 257 gen 548185 top level 5 path debian ID 289 gen 418851 top level 257 path var/lib/machines ID 299 gen 537230 top level 5 path boot ID 532 gen 502364 top level 257 path tmp/test1 ID 533 gen 502277 top level 532 path tmp/test1/test2 ID 534 gen 502407 top level 257 path tmp/test1.snap ID 535 gen 502363 top level 532 path tmp/test1/test3 ID 536 gen 502407 top level 257 path tmp/test1.snap2 ID 537 gen 537132 top level 5 path test ID 538 gen 537130 top level 537 path test/sub1 The root filesystem is mounted as mount -o subvol=debian .... I think that "btrfs sub list" is buggy, and it outputs a "top level ID" equal to the "parent ID" (on the basis of the code). But I am still asking which would be the RIGHT "top level id". My Hypothesis, it should be the ID of the root subvolume ( or 5 if it is not mounted). So the output should be ghigo@venice:~$ sudo btrfs sub list / [sudo] password for ghigo: ID 257 gen 548185 top level 5 path debian ID 289 gen 418851 top level 257 path var/lib/machines ID 299 gen 537230 top level 5 path boot ID 532 gen 502364 top level 257 path tmp/test1 ID 533 gen 502277 top level 257 path tmp/test1/test2 ID 534 gen 502407 top level 257 path tmp/test1.snap ID 535 gen 502363 top level 257 path tmp/test1/test3 ID 536 gen 502407 top level 257 path tmp/test1.snap2 ID 537 gen 537132 top level 5 path test ID 538 gen 537130 top level 5 path test/sub1 The subvolumes in the file system (mounted from /debian) are / ID = 5 /debian ID = 257 /debian/var/lib/machines ID = 289 /boot ID = 299 /debian/tmp/test1 ID = 532 /debian/tmp/test1/test2 ID = 533 /debian/tmp/test1.snap ID = 534 /debian/tmp/test1/test3 ID = 535 /debian/tmp/test1.snap2 ID = 536 /test ID = 537 /test/sub1 ID = 538 BR G.Baroncelli -- gpg @keyserver.linux.it: Goffredo Baroncelli <kreijackATinwind.it> Key fingerprint BBF5 1610 0B64 DAC6 5F7D 17B2 0EDA 9B37 8B82 E0B5 -- 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
