Tar file size

[Dennis Handly]

Yes:
fsadm -F vxfs -o largefiles /dev/vg109/lvol1

[Andrew Kaplan]

Just one bit of clarification on enabling largefiles...the filesystem is utilizing the full version of online vxfs. Can the change be made on the fly, or would it be better to unmount the logical volume, run the command, and then remount it? Thanks.

Hi (again) Andrew:

Yes, with OnlineJFS you can enable largefiles for the filesystem without unmounting.

Regards!

Standard tar can backup an unlimited number of files up to 2 GB each. The resultant tar archive (with all the files inside) can be terabytes in size. The limitation for tar refers to individual files that are included in the tar archive file. If the filesystem where the archive file is located does not support largefiles, then the archive will stop when it is larger than 2 GB. To see is you have largefiles enabled, use fsadm as in:

fsadm /var
fsadm: /etc/default/fs is used for determining the file system type

It can be done on the fly without OnlineJFS.

I've done fsadm without OnlineJFS, the last time someone made this statement.
