ext3 file size limitation?

K.C. Chan — Thu, 26 Jun 2003 14:36:20 GMT

Does any one know what the file size limitation is for an ext3 filesystem? Is it 2Gbytes? Thanks.

No, 2 Gigabytes is not the filesize limit on ext3. If recollection is correct, I've done files as big as 8 GB on a standard isntall Linux Red Hat 7.3 machine.

My biggest filesystem in production is 16 GB.

Mike,
The file size limit for 32 bit systems on ext3 is 2TB.
This depends on the kernel version also. The block device limit in 2.4 was 2TB. In 2.5 it is raised. So, 2.5 systems will support even larger files and on 64 bit systems it will be even more.

HTH,
Umapathy

Hello!

It's much more (i have about 1.3TB) and it can
be more.

More Accurate Data

FS (blocksize) Max file size max filesystem size notes
ext[23] (1k) 16G 2T Needs regular fsck, slow to create/check, wastes space
ext[23] (4k) 2T 16T (ditto)
JFS (4k) 9E 4 P Doesn't work if PAGESIZE != 4k; VM-friendly fsck
XFS 9E 9 E Backports to 2.4 available; VM-friendly fsck
ReiserFS3.5 2G 16T uses large amounts of physical memory for in-kernel bitmaps
ReiserFS3.6 1E 16T Not yet tested by PeterChubb
