With tar, it is possible to create a file over the FS limit of 2147483647bytes. However, most tool can't deal with such file. We can split such file using the "split" tool, however its impossible to restore the splited file components together.
The -M and -L option in tar are for stream tape, not for file. Does anyone got this problem and found a way to get rid of this stupid fs limit.
I need TAR to automaticaly split the archive when 2GB size is reached and continue on the next file.tar.1 file.tar.2 ...
I can't believe i'm the first that complaint about that!!!
If you have root permission, man ulimit, man bash (contains ulimit)
Are you using compression?
tar -j or
tar -z

I had the same problem trying to backup a system to a file. Ended up having to use ghost instead!=o(
ulimit looks as though it might help, if only I had known about that before

On my Mandrake 8.2, ulimit -a shows
core file size (blocks) 1000000
data seg size (kbytes) unlimited
file size (blocks) unlimited
max locked memory (kbytes) unlimited
max memory size (kbytes) unlimited
open files 1024
pipe size (512 bytes) 8
stack size (kbytes) 8192
cpu time (seconds) unlimited
max user processes 4095
virtual memory (kbytes) unlimitedI had an empty 3.8G partition so I cat'ed a file

I never got problem TARing my system since the past 5 years even with tar.gz file over 10GB. However i now need to crypt them with ccrypt.
Since the file is over the FS limit, all tools and server such as binsplit, ccrypt, cat, apache will stop when the 2147483747 bytes limit is reached.
I am able to split with "split" the encrypt them, but unable to restore them toghether in the tar ball.
I will take a look to ulimit today, but i doubt it can't change anything to the problem.

Hi Dlonra,
I am curently use this file on a RH6 ext2, but will verify on my RH8 ext3 file system this afternoon

I have no trouble with large files in ReiserFS. I have 2 tarballs over 8Gb, and one almost 5Gb that's gzipped.
Would it be possible to upgrade to ReiserFS? It would require a new kernel and some data shifting, which may just be more trouble than it's worth. Just upgrading to Ext3 will not fix your problem.

Jake:
Even on a ext2, tar can create such large file, but could you please try to "cat" the file to a test file.If it work on a riserfs, i will consider this as an interesting solutions.

The gzipped file wasn't created with tar z; it was gzipped later, so I would assume other system tools also work. I tried cat, redirecting the output to /dev/null, and there were no errors, so I'm assuming it worked.

Jake:
cat will not return error message, but silently assume the job is done when reaching 2147MB. Should cat to a file instead of /dev/null in order to test this fs limit.

Ok, this time I dumped the output into another file. When cat was done, ls -l reported exactly the same size for both files, and both files had the same MD5 hash.
