Hi,

Does LVM support files greater that = 2GB? 
I'm running the default LVM (1.0.3) on = RH8.  I currently have a 1.2TB LVM  ext3 filesystem = mounted.  If >2GB  file is supported, what changes need to = be made to my existing setup.


Thanks in advance.

As far as I know, RH8 is recent enough to fully support large files (greater than 2 GB), but maybe you are using some sort of application not ported still to support large files, or an application on your. I seem to remember that things like "old" cpio didn't support large files, check if this is the case with "strace", and look for file open()'s with flags O_LARGEFILE. From open(2): O_LARGEFILE On 32-bit systems that support the Large Files System, allow files whose sizes cannot be represented in 31 bits to be opened.

Other than not being larger than the blockdevice, and doesnt the blockdevice has a limit of 2T ? > As far as I know, RH8 is recent enough to fully support large files > (greater than 2 GB), but maybe you are using some sort of application > not ported still to support large files, or an application on your. > > I seem to remember that things like "old" cpio didn't support large > files, check if this is the case with "strace", and look for file > open()'s with flags O_LARGEFILE.

Maybe thats why i have some trouble with pipes for files larger than 2G JonB From mboxrd@z Thu Jan 1 00:00:00 1970 From: Jose Luis Domingo Lopez Subject: Re: [linux-lvm] LVM & LFS support Message-ID: <20030513190831.GA4777@localhost> References: <20030510155825.GA24798@localhost> <3EC0951E.90304@silicide.dk> Mime-Version: 1.0 Content-Disposition: inline In-Reply-To: <3EC0951E.90304@silicide.dk> Sender: linux-lvm-admin@sistina.com Errors-To: linux-lvm-admin@sistina.com Reply-To: linux-lvm@sistina.com List-Help: List-Post: List-Subscribe: , List-Unsubscribe: , List-Archive: Date: Tue May 13 14:08:02 2003 List-Id: Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: linux-lvm@sistina.com On Tuesday, 13 May 2003, at 08:47:58 +0200, Jon Bendtsen wrote: > Other than not being larger than the blockdevice, and doesnt the > blockdevice has a limit of 2T ? > Your are right. There has been native support for huge (huge is large than large :) block devices in 2.5.x for some time, and I think there is also a backport to 2.4.x (I suppose main Linux distributors have some sort of support for huge block devices, at least on their latest business-grade offerings).
