Is there really a number of mount points allowed on HP-UX?

Is there really a number of mount points allowed on HP-UX?

For eg:
vxfs mount: /dev/vg03/lvol3 is already mounted, /mountpoint3 is busy, or allowable number of mount points exceeded

If yes, how to check what's the number of mount points allowed on HP-UX?

There are usualy two problems associated with error. First is that you could have a duplicate minor number in the /dev/vg03 or the logical volume is already mounted. Do an 'ls -l' on /dev/vg03 to verify.

hi,

like what Michael say, it may have something to do with the minor number. read what HP Technical KB says:

http://www2.itrc.hp.com/service/cki/docDisplay.do?docLocale=en_US&docId=200000062908555

Thank you for the document. But the query here is: is there a number of mountpoints allowed on HP-UX which we may have exceeded?

If yes, how to check the number? Thanks.

[Michael Tully]

I have never seen a limitation on this, however that does not mean that there is one. Mind you I have worked on many unix systems where there have been more than 300 filesystems.

Thank you for your feedback on that you have worked on unix system more than 300 filesystems.

I really wonder if there's really a number of mountpoints allowed on HP-UX since the error message produce such possibility? If yes, how could we check on this number?

hi,

if there is one, i would like to know as well.

however, if 1 VG allows only maximum of 255 LVs, i guess the maximum mount points for each VG would be 255 then.

Hi,

There is a work around for this. Remove the directory, re-create it and mount the filesystem.

#rmdir /mountpoint3
You can even try rm -rf /mountpoint3
#mkdir /mountpoint3
#mount -F vxfs /dev/vg03/lvol3 /mountpoint3

regards,
RDL.
