This is a Seagate ST3000DM001, all one volume, for my sister's DVR on
which I've been doing this volume recovery work. The default setup that
mkfs.xfs returns with no parms supplies is this:
meta-data=/dev/sda1 isize=256 agcount=4, agsize=183141568 blks
= sectsz=4096 attr=2, projid32bit=0
data = bsize=4096 blocks=732566272, imaxpct=5
= sunit=0 swidth=0 blks
naming =version 2 bsize=4096 ascii-ci=0
log =internal log bsize=4096 blocks=357698, version=2
= sectsz=4096 sunit=1 blks, lazy-count=1
realtime =none extsz=4096 blocks=0, rtextents=0
and that takes about 3 minutes to mkfs a 3TB drive.
Anyone have some thoughts they wish to cast upon the waters about either part
of that?
Dave, Eric, and the rest of the xfs team will tell you "use the defaults
Luke". For 99 and 44/100ths percent of users, this is the right choice.
I am guessing that some of the delay may be the speed of the interface
to the disk ... but even then 3 minutes sounds long, unless something
else is hitting the disk at the same time.
Which kernel version btw? A quick 'uname -a' is a good thing.
Your hardware could also be somewhat slow ... Could you do an
lshw -class disk -class storage
