Hello.
I have a SCSI hard drive with two ext3 partition, mounted in /mnt/sdc1 and /mnt/sdc2.
They are configured so to be mount at boot time. This is their fstab entry:
Quote:
/dev/sdc1 /mnt/sdc1 ext3 defaults 1 2
/dev/sdc2 /mnt/sdc2 ext3 defaults 1 2
|
Whenever I start my system, they're properly mounted and works fine.
I have some files and dirs stored in this partitions, and run some programmes that reads and writes files in this drive.Usually, I run some programs that will keep running for a couple of days, and leave the office. Sometimes (not always), when I return to the office the next day, I can't find the drive. What does this mean? The dir still exist (/mnt/sdc1), but NOTHING is mounted over there, like if somehow the device has been unmounted. If I do a ls, I get
Quote:
[root@INTA01 mnt]# ls -l sdc1/
total 0
|
But I don't think that the disk is unmounting itself, because if I try to mount the device again over /mnt/sdc1, I get
Quote:
[root@INTA01 mnt]# mount -t ext3 -o defaults /dev/sdc1 /mnt/sdc1
mount: /dev/sdc1 already mounted or /mnt/sdc1 busy
mount: according to mtab, /dev/sdc1 is already mounted on /mnt/sdc1

Or if I do df:
Quote:
[root@INTA01 sdc1]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sda6 494M 226M 242M 49% /
/dev/sda1 99M 18M 76M 19% /boot
/dev/sdb1 33G 30G 1.5G 95% /db1
/dev/sdc1 68G 4.6G 60G 8% /mnt/sdc1
/dev/sdc2 68G 33M 64G 1% /mnt/sdc2
/dev/sda5 8.3G 7.5G 372M 96% /home
none 503M 0 503M 0% /dev/shm
/dev/sda2 23G 20G 1.7G 92% /usr
/dev/sda7 1004M 843M 110M 89% /var

but when I try to find the size of /mnt/scd1 I get
Quote:
[root@INTA01 mnt]# du -h
1.0K ./cdrom
1.0K ./floppy
4.0K ./sdc1
4.0K ./sdc2
1.0K ./test
12K .

Even more, if I look at the process table, I get for the programs running over that drive

If I shutdown and restart the system, the problem's solved, the partitions are mounted again and working fine.
All my other drives and partitions works fine.
If anyone have a clue, please help me. Thank you very much, and sorry for my poor english.
I'm using Fedora Core 4, with kernel
