It was very eager to kill the backup (tivoli storage manager) client. Haven't needed it so far on 2.6.8.1. > A little info on the hardware: > Big server Small server > ---------------------- ----------------------- > Intel Xeon Dual Athlon MP > 7 external SCSI disks 4 internal IDE disks > IBM hardware RAID Software RAID-1 + LVM > 600+ GB XFS ~150 GB XFS > 17+ M files ~1 M files Dual pentium-III (IBM x330) 2 TB Infortren Eonstore, fibre channel 500 GB in use ~5 M files Also have another dual Xeon (Dell PowerEdge 2650) with ~1 TB on XFS, but that's running 2.4.20-30.8.XFS1.3.1smp, and has never had any problems. > > Does anyone actually use XFS for serious file-serving?

NetApp? My impression so far has been more that the 2.6-series might not yet have been stable enough. Have had to be chasing the leading/bleeding edge to get away from the known problems. Was looking forward to a real "maintainer" taking over this series, but that doesn't seem to be happening.. -jf - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
