Today (Saturday) We will make some minor tuning adjustments to MySQL.

You may experience 2 up to 10 seconds "glitch time" when we restart MySQL. We expect to make these adjustments around 1AM Eastern Daylight Saving Time (EDT) US.


Unable to mount shared folder from Linux server

I'm still scratching my head on this one. Hopefully a HP-UX expert will chime in at some point.

Another thought is could the NFS versions on these systems be different???
Often you can specify the version (2, 3 or 4) on the 'mount' command line but I don't know whether that option (eg, '-o vers=3') is available in HP-UX. If the NFS versions are different then that will cause trouble.

Also, perhaps you should be putting '-F nfs' option on your mount command. Again, I'm not sure about HP-UX.

Also, I would think about setting the protection mask on the /public share to 777 until this issue is resolved to ensure security isn't getting in the way.

I'll continue to think about this one.

This page from the HP forum:

how to check NFS version - Hewlett Packard Enterprise Community

states that you can specify the NFS version to use on the mount command with '-o vers=<2, 3 or 4>'

Also it would be worth checking the supported NFS versions on all HP-UX boxes (in case they are different) and the Suse box.

Both server 10.1.2.6 and 10.1.2.8 has a NFS version 2 and 3, and the Linux has NFS version 2,3, and 4

I have tried to run
Code:
mount -o vers=3 10.1.2.82:/public /bkup

Still no success on 10.1.2.8 but success on 10.1.2.6
# 10  
Can you please post the subnet mask setting for each of your systems.

I just wonder whether the NFS mount request to 10.1.2.82 is actually reaching that box (but perhaps going out onto the internet). You say "all can ping 10.1.2.82". Can you prove that by downing/unplugging that box and check that a subsequent ping fails on all boxes.

You can use 10.x.x.x on your own network but you have to be sure it's configured correctly and all your boxes know that such addresses are on the local subnet.

As I say, I'm beginning to consider whether this is a network config problem and the NFS mount request is never reaching its target.

Hi,

I can't see anything obviously wrong in that.

Can you retrieve the MTU setting for all boxes?

(Which version of HP-UX are you using? I don't think you've said.)
