mounted fat32 filesystem becomes readonly after sometime, wierd?
Hi,
I have two fat32 partitions which I've mounted under /win1 & /win2 respectively. The lines corresponding to those in /etc/fstab are :
Code:
/dev/hda1 /win1 vfat defaults,umask=000 1 0
/dev/hda5 /win2 vfat defaults,umask=000 1 0
Now sometimes /win2 becomes readonly. I then have to unmount it and then mount it again. It works fine but then after sometime it becomes readonly again. I've had no problems with /win1. Don't know why this is happening. Any ideas ?
Thanks in anticipation.

No idea, but you may be able to grep through your dmesg to see if there are any corresponding entries for /dev/hda5 to help you diagnose the problem.
dmesg | grep hda5
dmesg | grep win2
You might also check your system log and see if /proc has anything about it. Check /etc/mtab after it gets mounted just to see if it actually is.
Lastly, are you sure it's becoming read-only, or is it just specific files?
Cool

Hi,
Thanks for the reply. I tried using dmesg but it's giving me problems as well. The output of dmesg is :
Code:
koodoo@knapsacker:~$ dmesg

NETDEV WATCHDOG: eth0: transmit timed out
eth0: Tx timed out, cable problem? TSR=0x6, ISR=0x0, t=24.
I checked the system log files. There were some message files that contained the following contents :
Code:
Nov 1 04:53:29 knapsacker kernel: 03:05: rw=0, want=1050881691, limit=9783553
Nov 1 04:53:29 knapsacker kernel: attempt to access beyond end of device

Nov 1 04:53:29 knapsacker kernel: attempt to access beyond end of device
I checked the file /var/log/dmesg. The only references to hda5/win2 that it contained were :
Code:
Partition check:
hda: hda1 hda2 < hda5 hda6 hda7 >
Ya, I'm sure it's becoming read-only, i.e. the entire filesystem and not just the individual files.
/etc/mtab shows that it's mounted when I mount it.
BTW If this might be useful, my system's been up for 9 days. Here's the output of uptime :
Code:
koodoo@knapsacker:~$ uptime
20:44:56 up 9 days, 8:50, 1 user, load average: 0.02, 0.08, 0.20
koodoo@knapsacker:~$
Thanks in anticipation.

Hi,
So I restarted my P.C. (after a long time). When I run the dmesg command I get a lot of output but there are only two lines repeated over and over again.
Code:
Neighbour table overflow.
NET: <some integer> messages suppressed.

Probably doesn't have anything to do with your FAT32 drive problem.

it may have been a cluster problem. i had the same problem and read a forum saying that using /sbin/fsck.vfat will remove the cluster problem. after i did it i had no more problems.
