Hello. Just want to create a to on my Redhat (REL5) Linux Media Server Creating file system for my MSDP pool, a 50TB (20 x 2.5TB LUNs). - And put it firmly that the ext4 file system sizes up to 16TB only unsterstützt. We have solved that? - Is there a way the MSDP foist multiple file systems? - Do you use Redhat Linux filesystems 16TB - If yes, which file system you use? Cortal Consors S.A.

Hello. Just want to create a MSDP filesystem on my Redhat (REL5) Linux Media Server about 50TB (20 x 2.5TB LUNs). But ext4 supports only 16TB filesystems :-( How do you solved this problem? - Is there a way to foist the MSDP Pool multiple file systems? - I think the MSDP Pool needs a single Filesystem. - Do you use Redhat Linux filesystems 16TB ? - If yes, which file system you use? thx Thomas Cortal Consors S.A.

Re: [Veritas-bu] Redhat Linux Media Server and MSDP Filesystem 16TB?
Make sure you’re using one of the later revisions of RHEL5 – ext4 was there but not fully supported until 5.6 I think. Recent chatter on a Linux mailing list I’m on noted that Redhat has chosen XFS as default for upcoming RHEL7. One of the reasons given by them was the 16 TB limit of ext4. While it may be that upstream versions of ext4 have gotten around this limit as suggested by Justin that doesn’t mean the version you have on RHEL5 or RHEL6 will incorporate such changes. RedHat starts with an upstream version and usually doesn’t change to a later upstream version within a major release (RHEL5 will usually have the same upstream version it started with and RHEL6 will usually have a later upstream version but stay with that through its life.) Instead they backport bug and security fixes from upstream into their version.

Hi, A newish kernel+e2fsprogs supports ext4 volumes 16TB. Beware though, 16TB is relatively new you may run into problems (I did in the past with a 60TB volume). I’d recommend looking at using XFS or, if EXT4 is needed, use volumes less than 16TB. Also I would not necessarily recommend it but you could create an mdadm-RAID 0 of the two volumes and format it as XFS, but you would be putting all of your eggs in one basket, e.g. if one of the 20 x 2.5TB LUNs failed, you would lose all of the data.

I subject you to look for VERITAS storage foundation. It is more robust and it has proven it, all these years. If I remember correct, you can install it for free with only one volume group. If you want you can pay for support.

The basic version of Storage Foundation will be perfect match for this requirement, it also contains VxFS that is way better file system than EXT4 (https://www.symantec.com/storage-foundation-basic) It is free for use up to 4 volumes for servers with up to 2 CPU HTH On Thu, Jul 11, 2013 at 10:39 PM, thomas.sch...@cortalconsors.de wrote: Hello.

Re: [Veritas-bu] Redhat Linux Media Server and MSDP Filesystem 16TB?
+1 for Storage Foundations - the only thing with it is to recognise that it can be finicky about kernels and other file dependences - but since you're only running a RHEL 5.x release, you should be fine. Best place to go, is the Symantec Storage Foundations for Linux site here - https://www.symantec.com/business/support/index?page=landingkey=15107 Oh, and the documentation site is very useful too - http://sfdoccentral.symantec.com/index.html Cheers John From: Mikhail Nikitin mikhail.niki...@gmail.com To: thomas.sch...@cortalconsors.de, Cc: Veritas-bu@mailman.eng.auburn.edu veritas-bu@mailman.eng.auburn.edu, veritas-bu-boun...@mailman.eng.auburn.edu Date: 12/07/2013 09:09 AM Subject:Re: [Veritas-bu] Redhat Linux Media Server and MSDP Filesystem 16TB?
