If I create a subvolume with a name longer than 4 characters it is read-only, if the name is shorter than 5 characters the subvolume is writeable as expected. I think it is since I upgraded to kernel version 2.6.38 (I do not create subvolumes on a regular basis.). I will compile one of the latest 2.6.37 kernels to see whether there the problem exists, too. Another interesting point is that previously created subvolumes are not affected. Thanks, Andreas Philipp thor btrfs # btrfs subvolume create 123456789 Create subvolume './123456789' thor btrfs # touch 123456789/lsdkfj touch: cannot touch `123456789/lsdkfj': Read-only file system -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iQIcBAEBAgAGBQJNia2nAAoJEJIcBJ3+XkgiTQQQAJqvn+zYbDmqmSo8ZRG86ssR Tj0hsaAYjSWiIUxs7Y9XulmC0sZoSpvX5BLIjW1pYwECzhzrA//pQrwVbXgwbW5H VjZ+YxcOcw4jxoUbW3lG+KYtSFMJFtbdMejmCY3GgYYIq1mtn0hBrCqZJ0syl4LO IjyTHR/v0r7FMIgL26F1jOfC478RfhIxAgZOtd65kl7/pHOv5At+99tgM4teUoy0 I76CWu6Ls9+1XevxMWp39XNceYCtQ/WoEThuQCvPERq6Th3NWczPBTP3POSBetVA Kcomq0TmgXQx1ZalFAFpMi9iRriDXbSm3ITSZW6Jp2BSEPurzpydchfhg0AWVNcC Icp5b+dy2RVM/K5UNDO6lNf8p+K1wk8GGpD/Pr+K0lO0FlKX+6rApzgx54GYL3cx 0RYL+NAAwSpy1i2uBIw72gyGX/yBliX7CB+YZZ/iULk0eUd36FvpJJAJ1Isk+QNn 6WFBoRwsMrL3WfiqR5/ODO+i+z+CUzYU0mUnD9IuQkdCANyXOeQhs5AyMOPkB1NC SS9ChpL60khwmLs9c99AyIzcvZU/q12JMvOZ2YUnfEHNIC/XmaThq11RbCIWIsl2 vjPr1QvKK+aykaOfjiTgLTwvB3mq147uEAylzIkduiQSFizMudbsI9vcO/X2pcy3 SVO9m6tlBUsCq3dU1dcA =NEEb -----END PGP SIGNATURE-----
