I have a large (105MB) data file, tab-delimited with a header. There are some odd characters at the beginning of the file that are preventing it from being read by R. > dfTemp = read.delim(filename) Error in make.names(col.names, unique = TRUE) : invalid multibyte string at '<ff><fe>m' When I...

...a "reasonable" level.( cpu at this hang time would be about 90-95% idle, and load would go from about 40-100) We then changed the 5i config to present each disk as a raid 0 device (no processing on the card now) and used Linux Raid to do the mirroring and raid5-ing. We now get about 100-105MB/s thoughput to the SW raid 5, and no more apparent hangs. If anyone is using a SmartArray device, you may want to experiment with SW raid instead. Dan Liebster Adecco

Hey, since RH took control of glusterfs, I've been looking to convert our old independent RAID storage servers to several non RAID glustered ones. The thing is that I, here and there, heard a few frightening stories from some users (even with latest release). Any one has experienced with it long enough to think one can blindly trust it or if it is almost there but not yet ready? Thx, JD

...k on its own, i.e. gluster volume create test-volume replica 2 transport tcp $(for i in b c d e f g h i j k l m ; do for n in 1 2; do echo -n "gluster0$n:/data-$i "; done; done) As expected, the overhead here is larger. initial file creation started slowly at 45MB/s and peaked around 105MB/s, 50 clients saw a total bandwidth of about 41MB/s (3) I ran other tests across all 10 backend bricks, but never went beyond ~ 80MB/s when using 4 disk raid0 over 10 servers. All tests were run with glusterfs 3.2.5 on Debian Squeeze, md-software raid, xfs file system, "default" sett...

Under Solaris 10 on a 4 core Sun Ultra 40 with 20GB RAM, I am setting up a Sun StorageTek 2540 with 12 300GB 15K RPM SAS drives and connected via load-shared 4Gbit FC links. This week I have tried many different configurations, using firmware managed RAID, ZFS managed RAID, and with the controller cache enabled or disabled. My objective is to obtain the best single-file write performance.
