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: http://kbase.redhat.com/faq/docs/DOC-9855 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): e2fsprogs-1.39-15.el5 How reproducible: 100% Steps to Reproduce: 1. Examine man pages or /usr/share/doc/e2fsprogs-*/* Actual results: No mention of use of -F to create large file systems Expected results: Document use of above switch Additional info:
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. Thanks, -Eric
Oh, and in fact it is already removed in e2fsprogs-1.39-22 as part of the changes for bug 241285. -Eric *** This bug has been marked as a duplicate of bug 241285 ***
