deleting a btrfs subvolume shut up a server
I created at a 3 TB btrfs formatted disk a btrfs subvolume, unpacked a minimal Gentoo Linux in it, created in addition few files within it under ./tmp and bind mount from the host few files onto those files. If I now delete in another terminal the subvolume - then the server dies immediately It is a headless server, I had to request a manually reset to get it back. Nothing in the syslog (syslog-ng 3.6.2) - the server was just shot in he head. This happened 2 times in a row. Host is a stable hardened Gentoo with 4.0.2 kernel. :-/ -- Toralf pgp key: 7B1A 07F4 EC82 0F90 D4C2 8936 872A E508 0076 E94E -- "; the past is all dirty and cruel in the modern popular imagination, with the exception of the Romans, who are just cruel" Ian Mortimer, 2008, "The Time Traveller's Guide to Medieval England" -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
deleting a btrfs subvolume shut up a server
I created at a 3 TB btrfs formatted disk a btrfs subvolume, unpacked a minimal Gentoo Linux in it, created in addition few files within it under ./tmp and bind mount from the host few files onto those files. If I now delete in another terminal the subvolume - then the server dies immediately It is a headless server, I had to request a manually reset to get it back. Nothing in the syslog (syslog-ng 3.6.2) - the server was just shot in he head. This happened 2 times in a row.
