nodatainlog - mount option

[Mariusz Grabowski_2]

Folks,

I have a system (hpux11i) where I mount a fsystem with 'delaylog,largefiles' options, but in 'mount -p' o/p I see:


/dev/vgxxx/lvyyy /ZZZZ vxfs delaylog,nodatainlog,largefiles 0 0

where does the 'nodatainlog' come from?

I've faced the same on hpux11.0 (it required to put 'vxadv' driver into kernel) - don't know though what's the matter here.

appreciate replies

cheers, Mariusz

Hi - not real sure what you're asking, if you're asking how to get rid of it, just edit the entry in /etc/fstab for that filesystem and specify datainlog and that will take care of it...if that's not your question, please clarify.

[Mariusz Grabowski_2]

well, seems i did not point my question exactly.

the thing is:

where does the 'nodatainlog' come from?

I use only 'delaylog,largefiles' options, and I get 'nodatainlog', which i don't want.

Mariusz,

The datainlog is only available with OnlineJFS, so I suspect you are defaulting to nodatainlog because you don't have OnlineJFS. See man 1m mount_vxfs.

Are you running onlineJFS?

If not, I don't believe that datainlog is available, so the default may be nodatainlog.

[Charles McCary]

Also, can you post your /etc/fstab entry for this filesystem?

[Alzhy]

online JFS or not (also full or non-Full VxFS or not) - nodatainlog will be the default. datainlog option however is only available with online JFS.

nodatainlog disables synchronous writes.

Read the man page mount_vxfs.

[Kevin Wright]

datainlog is default.

mount -o remount,delaylog,datainlog,largefiles /dev/vgxx/lvyyy /zzz

[Mariusz Grabowski_2]

I have onlinejfs on this server.

fstab shows:
# See fstab(4) and sam(1M) for further details on configuring devices.
/dev/vg00/lvol3 / vxfs delaylog 0 1
/dev/vg00/lvol1 /stand hfs defaults 0 1
/dev/vg00/lvol4 /lhome vxfs delaylog 0 2
/dev/vg00/lvol5 /opt vxfs delaylog 0 2
/dev/vg00/lvol6 /tmp vxfs delaylog 0 2
/dev/vg00/lvol7 /usr vxfs delaylog 0 2
/dev/vg00/lvol8 /var vxfs delaylog 0 2


while mount -p:
/dev/vg00/lvol3 / vxfs log 0 1
/dev/vg00/lvol1 /stand hfs defaults 0 0
/dev/vg00/lvol8 /var vxfs delaylog,nodatainlog 0 0
/dev/vg00/lvperf /var/opt/perf vxfs delaylog,nodatainlog 0 0
/dev/vg00/lvcrash /var/adm/crash vxfs delaylog,nodatainlog 0 0
/dev/vg00/lvol7 /usr vxfs delaylog,nodatainlog 0 0
/dev/vg00/lvol6 /tmp vxfs delaylog,nodatainlog 0 0
/dev/vg00/lvsec /secman vxfs delaylog,nodatainlog 0 0

[Pete Randall]

Then, since you do have OnlineJFS, I would presume that you have to use the "datainlog" option when mounting if that's what you want.

even when I use an option:

-o datainlog

mount -p still shows 'nodatainlog'.
I've tried unount/mount with the above option - still no luck

[Bill Hassell]

nodatainlog had to be added by one of your root users. The 'standard' mount option for a vxfs filesystem in fstab is delaylog. Everything else (rw, nodatainlog, blkclear, convosync, mincache, snapsize, nolog, largefiles, quota, etc) are listed in the mount_vxfs manpage. If this filesystem mounts without a problem, you have Online JFS installed. If it produces an error, just remove the option.

[Alzhy]

Use "datainlog" as it enhances your writes.

By default nodatainlog is enforcedd if not explicitly declared in /etc/fstab. Be sure though you have OnlineJFS.

[Alzhy · Accepted solution]

Mariusz -- then that means you do not have OnlineJFS installed.

What does:

vxlicense -p

return?

[Sandman!]

The "nodatainlog" option cannot be changed for a filesystem unless you have Advanced VxFS product installed. If you have BaseJFS then "nodatainlog" will remain the default and changing it on the command line will have no effect.

cheers!

"I've faced the same on hpux11.0 (it required to put 'vxadv' driver into kernel) - don't know though what's the matter here."

I should have noticed earlier.. it does appear you do not have OnlineJFS - aka Full or Advanced Veritas File SysteM (VxFS).

Do a vxlicense -p.

Depending on where you purchase your JFS/VxFS from - if it is from HP then you need to install the OnLineJFS product (which essentially does simply a copy of the license file).

If it is from Veritas (Full VxFS) .. then it is adding a license via the vxlicense command.

[Mariusz Grabowski_2]

I found the same:

when I tried to resize a fs, got a message:

fsadm: You don't have a license to run this program

[Pete Randall]

In that case, refer back to my first answer!

[Mariusz Grabowski_2]

it's not that obvious all right.. i have onlinejfs, something is screwed up with the lics though.

need to figure out the licensing then - thanks every1 for replies :)
