Answer Iomega® REV® drives use a unique disk format called the REV UDF format. The REV UDF format can support file sizes up to 8TB, which is much larger than a REV disk can actually hold. Any other file size limitations you may encounter are most likely due to various backup programs that have their own file size limitations, which are not related to the REV UDF file system format. Refer to the backup software vendor for more information regarding file sizes. A bugzilla entry for RHEL without an Issue-Tracker ticket will be taken as advisory. Six patches to fix some problems in UDF were posted to linux-kernel on March 6 2007 by Jan Kara of Suse but they have not been merged into the upstream kernel. Thread title is "UDF cleanup and fixes"; all six patches were acked by Christoph. Jan has since posted a couple other patches in addition to that patchset, but they still have issues (deadlocks) the 1Gb limit was imposed some time ago as a quick fix for a security problem (CVE-2006-4145). Jan's patchset is almost ready to go, and will make it to RHEL5 when it's ready. fyi fc6 kernel-2.6.20-1.2962.fc6 >1 gb is ok rhel 5 server kernel-2.6.18-8.1.8.el5 max filesize =1gb fyi
rhel 5 server
kernel-2.6.18-8.1.10.el5
max filesize = 1gb
fc6
kernel-2.6.22.5-49.fc6
> 1 gb is ok
Yep, the newer kernels have the fix to safely allow >1gb again. I have another bug open (should probably dupe this to that, or vice versa) to get the upstream fix into RHEL5. Thanks, -Eric *** Bug 251127 has been marked as a duplicate of this bug. *** Upstream patchset for this has had quite a lot of soak time, and I've worked w/ Jan to iron out a couple issues. Would like to see this for 5.2. Thanks, -Eric This request was evaluated by Red Hat Product Management for inclusion in a Red Hat Enterprise Linux maintenance release. Product Management has requested further review of this request by Red Hat Engineering, for potential inclusion in a Red Hat Enterprise Linux Update release for currently deployed products. This request is not yet committed for inclusion in an Update release. in 2.6.18-61.el5 You can download this test kernel from http://people.redhat.com/dzickus/el5 thanks, no problems here on a test machine tar-file >40gb added to RHEl5.2 release notes under "Resolved issues": <quote> REV UDF file sizes larger than 1GB are now supported. </quote> Hi, the RHEL5.2 release notes will be dropped to translation on April 15, 2008, at which point no further additions or revisions will be entertained. a mockup of the RHEL5.2 release notes can be viewed at the following link: http://intranet.corp.redhat.com/ic/intranet/RHEL5u2relnotesmockup.html please use the aforementioned link to verify if your bugzilla is already in the release notes (if it needs to be). each item in the release notes contains a link to its original bug; as such, you can search through the release notes by bug number. Cheers, Don intranet.corp.redhat.com is not reachable via internet host redhat.com has address 209.132.177.50 host corp.redhat.com has address ?? host intranet.corp.redhat.com has address ?? comment #25 was most likely intended for an internal audience, sorry about that. I was able to copy a 1.3GB file to a udf filesystem mounted on a loopback device. It was extremely slow, but eventually it got there so I think this particular bug is fixed. An advisory has been issued which should help the problem described in this bug report. This report is therefore being closed with a resolution of ERRATA. For more information on the solution and/or where to find the updated files, please follow the link below. You may reopen this bug report if the solution does not work for you. http://rhn.redhat.com/errata/RHBA-2008-0314.html |
