problem with largefiles option

Lukasz_6 — Tue, 11 Oct 2005 04:01:14 GMT

Hi,

I have created new FS with largefiles option:

newfs -F vxfs -o largefiles /dev/vg01/rlvol1

now I am trying to mount this fs with largefiles option it doesnt wor.

mount -F vxfs -o delaylog,largefiles /dev/vg01/lvol1 /mount_point

When I am mounting FS I have no errors but when I type mount -p it seems that FS is mounted only with delaylog option:

/dev/vg01/lvol1 /mount_point vxfs delaylog 0 0

What does mkfs -m /dev/vgxx/rlvolx say?
does it show that FS was created with largefiles option?

What does mount -v say??

Did you try creating 2GB file and see??
prealloc 2000000000

Hi,

Could you post the output of,

# fsadm /mount_point
or
# fsadm /dev/vg01/rvol1

Regards,
Robert-Jan

Hi,

The steps are :

Creation of a filesystem with large file option:
/usr/sbin/newfs -F vxfs -o largefiles /dev/[vg]/[rlvol]

Changing an existing filesystem to largefiles:
/usr/sbin/fsadm -F vxfs -o largefiles /dev/[vg]/[rlvol]

Mounting the filesystem:
mount -F vxfs -o largefiles /dev/[vg]/[lvol]/[mountpoint]

Entry into /etc/fstab (e.g.):
/dev/vgxx/lvolx /[mountpoint] vxfs delaylog,largefiles 0 2

Checking up if large file option has been activated:
fsadm -F vxfs/dev/vgxx/rlvolx

Hope this information can help you.

Cheers,
AW

output:

#fsadm -F vxfs /dev/vgsmac256/rpoldb
nomultifsets
largefiles

I have tried to unzip file that is larger then 2gb:

# gzip -d CMS_dump071005_04.dmp.gz
gzip: CMS_dump071005_04.dmp: File too large

# mount -p | grep poldb
/dev/vgsmac256/poldb /smac/poldb vxfs delaylog 0 0

there is no way to mount this FS with largefilest option, I have tried many times to unmount and mount this FS
any ideas?

Before mounting file system convert file system with large files support fsadm.

See man fsadm for more details.

To get verbose with mount use as,

# mount -v -F vxfs -o delaylog,largefiles /dev/vg01/lvol1 /mount_point

hth.

What does following command return???

mkfs -m /dev/vgxx/rlvolx

Re: problem with largefiles option

#mkfs -F vxfs -m /dev/vgsmac256/rpakdb

It was indeed created with largefiles option. But looks that is not mounted with largefiles option.

Unmount and mount with largefiles option.

mount -F vxfs -o largefiles,delaylog /dev/vgxx/lvolx /mount_point

mount -v

Does it get mounted with largefiles option??

The filesystem is not the problem. You are using a 32 bit version of gzip which cannot seek more than 2Gb.
You can get round this by reading the file contents using re-direction from stdin (< or cat | ) then re-directing the output using >

Then you need to install a 64 bit version of gzip.

No need to specify largefiles with -o option using mount command. It will take based on fsadm or mkfs utlities.

Refer:

The mount command uses the same two options as the mkfs, newfs, and fsadm commands (largefiles and nolargefiles). mount will not mount a large-files file system if the -o nolargefiles option is specified. Conversely, the mount command will not mount a no-large-files file system if the -o largefiles option is specified. If no option is provided to mount, it will use the state of the file system itself to determine if it is mounted as largefiles or nolargefiles.

Once you are changing with fsadm / mkfs then mount with delaylog option with -o only.

hth.

All that you are saying is true, but it still doesn't work :)

I am using 64bit zip so it is problem with largefiles option.

The mount_vxfs command usage (as displayed in your response earler and the man page) appears to show that -v -F are not supported in the same command - so leave out the -v.

mount -F vxfs -o largefiles,delaylog lvol mountpoint

I still think you will have a problem with gzip as well, unless you are sure you installed the 64 bit version.

Re: problem with largefiles option

Muthukumar_5 — Tue, 11 Oct 2005 05:20:20 GMT

# fsadm -F
# mount -e -F vxfs -o delaylog lvol mountpoint

-e verbose mode

# fsadm -F vxfs Mount-point

What are you getting there?

You can also try with,

sam -> disks and filesystems -> file systems

hth.

Have you tried ...

# gzcat CMS_dump071005_04.dmp.gz > CMS_dump071005_04.dmp
