Test result: Without the patch: [root@cluster1 gfs]# time dd if=/dev/zero of=/mnt/gfs1/bigfile bs=1024k count=1000 real 1m34.196s user 0m0.010s sys 1m29.660s With the patch: [root@cluster1 gfs]# time dd if=/dev/zero of=/mnt/gfs1/bigfile bs=1024k count=1000 real 0m20.875s user 0m0.001s sys 0m4.449s Just in case someone wants to build the GFS module without formal GFS RPMs, the above patch had a typo: error = filemap_fdatawrite(ip->i_gl); should have been error = filemap_fdatawrite(file->f_mapping); Checked into CVS. An advisory has been issued which should help the problem described in this bug report. This report is therefore being closed with a resolution of ERRATA.
