topic snapshot question in Operating System - HP-UX

snapshot question

Thanh Nguyen_2 — Mon, 13 Aug 2001 19:42:00 GMT

Hi all
I'm new to HP-UX (11.00) in general and the OnlineJFS product in particular. My question is this: I just installed the OnlineJFS product (B.11.00) on top of the base product (also B.11.00). It installed and compiled the kernel and rebooted OK. I then created a logical volume (lvcreate) in vg00 called "testsnap" successfully. A mountpoint /testsnap was also created OK. Here's the command I used to create a snapshot:
# mount -o snapof=/u01 /dev/vg00/testsnap /testsnap

and it came back with:
vxfs mount: option not supported on this version of vxfs.

My "swlist -l product" command showed that the AdvJournalFS product is installed. This is probably some trivial thing that I missed.
Any suggestions?

Thank you

Hi Thanh:

I think all you need to do is change the command to include -F vxfs; an explicit -F vxfs is required when using the snapof= option.

Hi Clay
I did that also. "-F vxfs" did not help. Same error.

Before loading the Online JFS product, did you have PHKL_18543 installed?
If so, in the text file for thispatch is the wording:

Special Installation Instructions:
If PHKL_18543 is installed on a system that does not have
Advanced VxFS, then the Advanced VxFS driver 'vxadv' will be
commented out of the /usr/conf/master.d/vxfs file as follows:

* Disabling AdvJournalFS: vxadv vxadvc 10 100 ...

The following note will be logged in the swagent.log file:

NOTE: "AdvJournalFS" product is now disabled. Any vxadv driver in
the system file will be ignored. If you install the 11.00
version of "AdvJournalFS", you must again install this patch,
PHKL_18543.
(The reinstall* options must be set to false - the default.)

If the Advanced VxFS product is subsequently installed, PHKL_18543
must be reinstalled as specified in the note above, otherwise the
following warning will occur when creating a kernel and the Advanced
VxFS features will not be available:

WARNING: No such device, tunable, or cdio vxadv.
Ignoring the following line.
vxadv

Please apply this patch along with command patch PHCO_13411.
Failure to do so, ie. applying one without the other, will
result in fsck failure, or even fsck corrupting the
filesystem.

So I would check this first

You would also need to ensure you have the following patches or their superseding patches.:

Install the remaining HP-UX 11.0 Advanced VxFS patches:

PHKL_13203
PHKL_18532
PHKL_15940
PHKL_19135

Install the Advanced VxFS patch dependencies:

PHKL_17038
PHCO_17556
PHCO_17792
PHKL_18543
PHKL_19169
PHKL_18543
PHKL_17038
PHCO_17556
PHCO_17792
PHKL_19169

Thanks Melvyn. I think that's it. I'll see if it works and report back later.

Hi guys
After countless hours of tracking the patches, here's the latest list:
PHCO_23651 PHKL_15940 PHKL_20411 PHKL_24027 PHKL_24753
PHCO_23876 PHKL_18543 PHKL_22208 PHKL_24745 PHKL_24826

snapshot works fine now. And BTW, that PHKL_18543 is A PAIN.

Thanks guys
