While in IBM class we found we could create and use XFS under SLES 9 SP4, so it appears that while we are SLES 9 SP3 (where xfs is supported), there is something we are missing.

This is the resulting output from 'mkfs': ---(begin) mkfs.xfs: warning - cannot set blocksize on block device /dev/dasdd1: Invalid argument Warning: the data subvolume sector size 512 is less than the sector size reported by the device (4096). meta-data=/dev/dasdd1 isize=256 agcount=8, agsize=75102 blks = sectsz=512 attr=0 data = bsize=4096 blocks=600816, imaxpct=25 = sunit=0 swidth=0 blks, unwritten=1 naming =version 2 bsize=4096 log =internal log bsize=4096 blocks=2560, version=1 = sectsz=512 sunit=0 blks realtime =none extsz=4096 blocks=0, rtextents=0 mkfs.xfs: pwrite64 failed: Invalid argument mkfs.xfs: read failed: Invalid argument ---(end) A valid xfs filesystem is not written to disk, despite the output describing the resulting filesystem characteristics. Specifying '-s size=4096' results in a valid filesystem, and this output: ---(begin) meta-data=/dev/dasdd1 isize=256 agcount=8, agsize=75102 blks = sectsz=4096 attr=0 data = bsize=4096 blocks=600816, imaxpct=25 = sunit=0 swidth=0 blks, unwritten=1 naming =version 2 bsize=4096 log =internal log bsize=4096 blocks=2560, version=2 = sectsz=4096 sunit=1 blks realtime =none extsz=4096 blocks=0, rtextents=0 ---(end) If I attempt to create the filesystem on the non-partitioned disk device (/dev/dasdd) rather than the partitioned disk device (/dev/dasdd1), I get the same output as above (no errors), but the device is unmountable. I would second Mark Post's suggestion that a whole-disk partition be created with 'fdasd -a' and the filesystem be created on that device instead (/dev/dasdj1). ok r. > -----Original Message----- > From: Fargusson.Alan [mailto:[EMAIL PROTECTED] > Sent: Friday, March 14, 2008 10:54 AM > To: [email protected] > Subject: Re: Using xfs file sys > > I don't think the DASD driver supports setting the sector size.
