Document use of mke2fs -F for creating large file systems
Last modified: 2009-04-18 10:17:07 EDT
Description of problem:
It is now possible to create ext3 file systems of 8-16TiB in size (>2^31-1 blocks) by specifying the '-F' switch to the mke2fs/mkfs.ext3 command. This is documented in the following kbase note:
But is not mentioned in the documentation for the e2fsprogs package itself.
The larger file system size limits are fully supported as of RHEL-5.1 so it would be useful to have this documented. E.g. adding the following extra statement to the existing documentation of -F in man 8 mke2fs:
-F Force mke2fs to run, even if the specified device is not a block
special device, or appears to be mounted. This option is required
to create file systems larger than 8TB.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Examine man pages or /usr/share/doc/e2fsprogs-*/*
No mention of use of -F to create large file systems
Document use of above switch
Yep, we should fix this up. Since > 8T is supposed to be formally supported, we should just remove the need for the "-F" in the >8T case, I suppose.
Oh, and in fact it is already removed in e2fsprogs-1.39-22 as part of the changes for bug 241285.
