Hi, monks!

I had discovered all site with "unlink" keyword, but found nothing.

My question is:

Linux tkdrzbkup2.nssmb.com 2.4.18-12smp #1 SMP Fri Jun 14 15:22:49 EDT 2002 i686Linux,Red Hat 7.1, ReseirFS

root@tkdrzbkup2 staging# dd if=/dev/zero of=big_file bs=1M count=3072

3072+0 records in

3072+0 records out

root@tkdrzbkup2 staging# pwd

/export/staging

root@tkdrzbkup2 staging# mount

/dev/rza1 on / type ext2 (rw)

/dev/rze1 on /export type reiserfs (rw)


root@tkdrzbkup2 staging# ls -l

-rw-r--r-- 1 root root 3221225472 Nov 12 09:56 big_file

root@tkdrzbkup2 staging# perl -e 'printf "Deleted %d files\n", unlink "/export/staging/big_file"'"'

Deleted 0 files

For checking:

root@tkdrzbkup2 staging# ls > a

root@tkdrzbkup2 staging# ls -l

total 3148804

-rw-r--r-- 1 root root 11 Nov 12 13:33 a

-rw-r--r-- 1 root root 3221225472 Nov 12 09:56 big_file

root@tkdrzbkup2 staging# perl -e 'printf "Deleted %d files\n", unlink "/export/staging/a"'

Deleted 1 files

Command 'rm':

root@tkdrzbkup2 staging# rm -f big_file

root@tkdrzbkup2 staging# ls -l

total 0

It means, unlink doesn't work with big files.

Perl info:

root@tkdrzbkup2 staging# perl -V
