[CentOS] centos 6.2 xfs + nfs space allocation
Centos 6.2 system with xfs filesystem. I'm sharing this filesystem using nfs. When I create a 10 gigabyte test file from a nfs client system : dd if=/dev/zero of=10Gtest bs=1M count=1 1+0 records in 1+0 records out 1048576 bytes (10 GB) copied, 74.827 s, 140 MB/s Output from 'ls -al ; du' during this test : -rw-r--r-- 1 root root 429170688 Jun 8 10:13 10Gtest 654456 10Gtest -rw-r--r-- 1 root root 1756831744 Jun 8 10:13 10Gtest 2230720 10Gtest -rw-r--r-- 1 root root 2492145664 Jun 8 10:11 10Gtest 4348288 10Gtest -rw-r--r-- 1 root root 4686782464 Jun 8 10:11 10Gtest 8542592 10Gtest -rw-r--r-- 1 root root 1048576 Jun 8 10:12 10Gtest 1694355210Gtest The file is using almost double the size ? Even after a few days the file is showing the same disk usage. Only umounting and remounting the filesystem fixes the problem. When I do the same test on an ext4 filesystem no issues. (same server/client) Same issue on 2 centos 6.2 servers. I also tried to reproduce the issue on an rhel 5.8 system with xfs, but here the disk usage is ok. (I don't have a rhel6 systems with the xfs addon subscription) Stephan ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

I'm also running xfs_fsr /dev/VolGroup01/LogVol00 weekly, which doesn't help. P.S. you can also see the allocated size of a file using the -s option to ls Thanks, this shows the same info as du.

And ls -l shows 1048576 Would you like more info on my system? aurf, Any updates not installed on your system ? (older kernel maybe?)

[CentOS] centos 5.2 / sun java ?
Starting with rhel 5.2, Redhat provides sun java in the Supplementary channel. Are there any plans to release sun-java in the centos extra or plus repo ? Would be nice to keep sun java up to date using yum. Thnx, Stephan ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
