Subject: Bug#661580: mkfs.xfs fails to detect correct sector size
Date: Tue, 28 Feb 2012 08:49:14 +0100 [thread overview]
Message-ID: <20120228074914.31280.78231.reportbug@frosties.localnet> (raw)
Package: xfsprogs
Version: 3.1.7
Severity: important
File: /sbin/mkfs.xfs
Hi,
since I recently bought a harddisk with 4K sector size I've been
checking for correct alignment and blocksizes in various things. One
of them being xfs.
When I partition the disk in parted it shows correctly to have a
logical blocksize of 512 byte and physical blocksize of 4096 byte.
But mkfs.xfs does not detect that the physical blocksize is 4096 byte
and creates a filesystem with:
meta-data=/dev/sde1 isize=256 agcount=32, agsize=22892696 blks
= sectsz=512 attr=2
data = bsize=4096 blocks=732566272, imaxpct=5
= sunit=0 swidth=0 blks
naming =version 2 bsize=4096 ascii-ci=0
log =internal bsize=4096 blocks=357698, version=2
= sectsz=512 sunit=0 blks, lazy-count=1
realtime =none extsz=4096 blocks=0, rtextents=0
This often results in access to the disk that is not aligned to the
blocksize with the resulting degradation in performance.
Further, manually selecting the right sector size of 4096 still causes
lots of unaligned access while formating and while mounting the
filesystem. It does seem to fix the problem for actual use though.
