Linux support for large volumes

admin1979 — Thu, 28 Jan 2010 08:08:36 GMT

Hello,

We have a United Linux 1.0 system. We want to know the maximum size of partitions that Kernel 2.4 (2.4.21) would support.
We wish to create a local partition size of more than 300/400 GB. Would kernel give any sort of problems?

Secondly, In case of NFS shares. If NFS share of size lets say 500 GB is mounted on a server (kernel 2.4), would is support this NFS partition ??

Please let me know if you require anymore details.

Thanx,
admin

Additionally , we are using following hardware RAID on the system.

RAID bus controller: LSI Logic / Symbios Logic PowerEdge Expandable RAID Controller 4 (rev 01)
Subsystem: Dell Computer Corporation PowerEdge Expandable RAID Controller 4/DC

Thanx,
admin

you can use 500GB volume w/o problem.
please specify your filesystem, but I guess any modern fs will support 500GB volume w/o problem.
for example, ext3 - http://en.wikipedia.org/wiki/Ext3

The filesystem in question is xfs.

My second question was for NFS. When a share is mounted using NFS, which filesystem limit should come into picture? for the local filesytem or the NFS filesystem?

Thanx,

The NFS server filesystem, although the NFS protocol will impose some file size restrictions depending on it's version (eg. NFSv2 is limited to 2GB).

Maybe you are talking about the individual file size. which is 2 GB for NFS2.
what about the filesystem size that is supported?

Yes, that's what I meant: individual file size might be restricted, but filesystem size is entirely dependant on the filesystem used on the NFS server, not the client's.

you won't reach XFS limits soon - http://en.wikipedia.org/wiki/Xfs :-)

there is no problem with such small filesystems.
you're running on old linux kernel though. is this still supported at all?

As mentioned above.
