Solaris 8 disk error

UNIX Solaris
1

Hello,

We are running solaris 8 and there is a disk having problem with consistency

The following devices (soft partitions from NetApp are inconsistent, unable to be repaired with fsck and need to be restored:

root@server1 # df -k
Filesystem            kbytes    used                   avail   capacity       Mounted on
/dev/md/dsk/d109     0     18446744071727368822 1982182794  0% /opt/mix

And when i look into the /opt/mix mount point it has no data in it,

root@server1 # cd /opt/mix
root@server1 #ls -al
total 0

Can anyone help what has happened to the disk , as it shows no files but its used capacity is 18446744071727368822 ( so much).

Looks like there was forced fsck run on the filesystem earlier.Any help will be greatly appreciated

One common way to get into this state is for a process to open and write data into a huge file and continue writing into it while it runs. (Although I didn't remember the kblocks field being 0 in this case.) Then another process removes that file (while it is still being held open by the first process).

In this case, the file data still resides on the disk even though it no longer has a name that appears in the file hierarchy. The file data will not be release until the process that has the file open closes it.

Forced fsck was run.

Anything in Lost+Found?

If fsck was run on /dev/md/dsk/d109 (i.e. /opt/mix ) and something had been placed in Lost+Found , wouldn't the ls output shown in post #1 in this thread have to include the directory Lost+Found ? Instead it shows that not even . and .. exist. Something like an

rm -rf /opt/mix

must have been run by root after the filesystem was remounted after the fsck to get something this messed up (and I thought even that should have failed for a mount point).

@Don.....I agree that this is a mess. What puzzles me is that the 'df -k' only shows one mounted filesystem. No sign of the root filesystem!

I also jumped to the conclusion, perhaps incorrectly, that /opt/mix being empty was due to that filesystem failing to mount. There's nothing under the mount point (or shouldn't be) until the filesystem is mounted under it.

I reckon that the 'df -k' is telling lies. The root filesystem has to be mounted otherwise the system wouldn't be up.

Perhaps the root filesystem is full to the extent that the system only just boots and can't mount any non-root filesystems.

What do you think?

I think we need more info here. Is that really the only output from 'df -k' or has it been edited? What files are visible on the root filesystem? Is there anything in Lost+Found on root?
