Hi gang!

I've just tried to build a Loopback FS, and I used the option "ro" not knowing what it was meaning, as in the example I have for this feature...

and of course now I'm stuck with my LOFS which is read-only... not really what I want to have

I tried to chmod it with no success (loggued as root)

How can I manage to remove it?

(and next time I will create it without the "ro" option)

Thanx

Have you tried remounting read-write?
I do not have a Solaris box to test this on, unfortunately.

Otherwise, can you not just umount it and then mount again?

Cheers

thanx for your help, I tried to remount it with no success it only answered and for umounting it, it doesn't work but I do it like to umount a standard mount, not a LOFS, may be there is special command line to umount a LOFS?

this is what is in my mnttab:

Maybe somebody is using a file on /myrep (or you or somebody else have a pwd of somewhere under /myrep).

Try fuser /myrep to see what processes are using the fs. If you don't have fuser try lsof.

With fuser you can supply the -k option to send a SIGKILL out to any processes using the mount (e.g. fuser -k /myrep) - be careful though - you could boot people off the system (yourself included) and cause file corruption if somebody is for example editing a file, leave child processes, not cleanup after itself, etc, etc, etc.

Once you get a "clean" output from fuser /myrep that nobody is using the mount, remount it rw.

ok

nothing

I grepped on /myrep and there are two java processes dealing with files among /myrep

If I understand correctly, I should manage to get rid of those processes in order to umount

(so I have to stop the software which run those processes... let's see if it is possible)

thanx again for helping

now it is ok, no more processes running and nobody accessing /myrep

I tried:

mount -F lofs -o rw /myrep /my_image_rep

-> Device busy (but nothing in fuser or lsof)

I tried several ways being at the same level than my_image_rep, being one rep higher and doing it like mount -F lofs -o rw /myrep rep_higher/my_image_rep

obtaining results like
mount: mount-point my_image_rep is not an absolute pathname.

mount: mount-point /my_image_rep does not exist.

and also every way of umount including with the -f option on what is in my mnttab (concerning /myrep)

I think I will end to rebuild the package I try to deploy using another directory than the one actually declared (my_image_rep)

but it will not fix the ro state of the actual my_rep_image in which I also have other packages installed (meaning that the other softwares will have troubles)

one colleague of mines suggest me to edit mnttab directly and to change ro in rw, any chance to succeed that way?

Have you umounted before trying to mount again? You could add the remount option as I showed earlier.

Otherwise if the box isn't critical - just reboot the thing that'll unmount it (as long as it isnt in /etc/vfstab)!
