https://bugzilla.kernel.org/show_bug.cgi?id=53951 Summary: race condition on mounting local disks with autofs Product: File System Version: 2.5 Kernel Version: 3.7.7 Platform: All OS/Version: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: ext4 AssignedTo: fs_ext4@xxxxxxxxxxxxxxxxxxxx ReportedBy: harri@xxxxxxxxx Regression: No I am using autofs to mount a local disk to /misc/data6 on request. Problem: It seems that the first access silently fails, if the disk is not yet mounted. Below is an example. Before running it I had umounted /misc/data6 and restarted autofs. % find /misc/data6 | wc -l; find /misc/data6 | wc -l 18 find: `/misc/data6/lost+found': Permission denied 358 As you can see, the first "find" sees just a subset of the directory entries. The second "find" stumbles over lost+found (as expected) and finds all entries. Kernel is 3.7.7. There is no error message in kernel.log, only a line to mention the mount: EXT4-fs (sdd1): mounted filesystem with ordered data mode. Opts: (null) /etc/auto.master: /misc /etc/auto.misc /etc/auto.misc: data1 -fstype=auto,noatime :/dev/disk/by-label/data1 data2 -fstype=auto,noatime :/dev/disk/by-label/data2 data3 -fstype=auto,noatime :/dev/disk/by-label/data3 data4 -fstype=auto,noatime :/dev/disk/by-label/data4 data5 -fstype=auto,noatime :/dev/disk/by-label/data5 data6 -fstype=auto,noatime :/dev/disk/by-label/data6 data7 -fstype=auto,noatime :/dev/disk/by-label/data7 data8 -fstype=auto,noatime :/dev/disk/by-label/data8 The problem is reproducible, as it seems. Please mail if I can help to track this down.
