How can I test if a subvolume is a snapshot? Example:
/test/.snapshot/2017-09-08_1037.single is a snapshot (of /test) /test/data is a regular subvolume I know this, because I have created them with suitable names :-) But how can I see/test it? root@fex:~/bin# btrfs subvol show /test/.snapshot/2017-09-08_1037.single /test/.snapshot/2017-09-08_1037.single Name: 2017-09-08_1037.single UUID: eff1cebb-b885-6b47-ae69-36a7c3f266eb Parent UUID: - Received UUID: - Creation time: 2017-09-08 10:37:04 +0200 Subvolume ID: 354 Generation: 237 Gen at creation: 237 Parent ID: 5 Top level ID: 5 Flags: readonly Snapshot(s): root@fex:~/bin# btrfs subvol show /test/data /test/data Name: data UUID: b32a5949-dfd6-ef45-8616-34ae4cdf6fb8 Parent UUID: - Received UUID: - Creation time: 2017-09-06 18:30:33 +0200 Subvolume ID: 257 Generation: 224 Gen at creation: 8 Parent ID: 5 Top level ID: 5 Flags: - root@fex:~/bin# btrfs subvol show /test /test is toplevel subvolume -- Ullrich Horlacher Server und Virtualisierung Rechenzentrum TIK Universitaet Stuttgart E-Mail: horlac...@tik.uni-stuttgart.de Allmandring 30a Tel: ++49-711-68565868 70569 Stuttgart (Germany) WWW: http://www.tik.uni-stuttgart.de/ REF:<20170908085446.ga7...@rus.uni-stuttgart.de> -- 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
