| |
[1.] One line summary of the problem:
when using 'mkdir' to create a directory on an ext3 filesystem, a regular file is created instead of the directory.
[2.] Full description of the problem/report:
I discovered this whilst writing a perl script, however, the problem seems to be the same within a normal shell also. I was trying to create a directory (in this case '.variable' off of my home dir) with the command 'mkdir .variable'. When I then tried to 'cd .variable' I received the error '-bash: cd: .variable: Not a directory'. The file or directory '.variable' did not exist prior to this. To make sure, I then executed the command 'rm -rf .variable' before trying the command sequence again, with the same results.
I attempted this approximately 20 times as a test to see if it was a permanent error or occasional, I also tried different directory names ('.variable', 'variable', 'test' & '.test'). In each case I managed to experience the problem, I also noted that approximately 1 time out of 10 the mkdir worked as expected.
The root superuser does not appear to be affected by this problem.
[3.] Keywords (i.e., modules, networking, kernel):
ext3, mkdir, directory
[4.] Kernel version (from /proc/version):

[7.6.] SCSI information (from /proc/scsi/scsi)
Attached devices: Host: scsi0 Channel: 00 Id: 00 Lun: 00 Vendor: SIIG Model: CompactFlash Car Rev: 0113 Type: Direct-Access ANSI SCSI revision: 02
[7.7.] Other information that might be relevant to the problem (please look in /proc and include all information that you think to be relevant):
The PC is an IBM Thinkpad T21.
A friend also experienced the same problem, he is also using the ext3 filesystem which is the only commonality we can think of.
Currently I have the following filesystems mounted (if its relevant?):
root@voyager scripts # mount /dev/hda4 on / type ext3 (rw,noatime) proc on /proc type proc (rw) none on /dev type devfs (rw) tmpfs on /mnt/.init.d type tmpfs (rw,mode=0644,size=2048k) /dev/hda1 on /mnt/win type ntfs (ro,uid=1000,gid=100) tmpfs on /dev/shm type tmpfs (rw) //defiant/drive_c on /home/russ/defiant type smbfs (0)
[X.] Other notes, patches, fixes, workarounds:
The aforementioned friend managed to circumvent the problem by cd'ing to another directory then back again. I tried this, which allowed me to mkdir one directory fine, but then the problem returned.
I also noted that root does not seem to be affected by this problem, I cannot reproduce it at all as root.
