Hi, all --
I finally settled on xfs as the filesystem for my raid5 volume on my
home computer even though I've been a longtime reiserfs lover :-) But,
hey, let's try something new.
I recently added another device to my md raid5 set and expanded the
device from 8T to 12T, and now I want to grow the filesystem. I remade
the partition and we oughta be good to go:
diskfarm:root:10:~> parted /dev/md0 print | egrep 'TB|Table|Sector'
Disk /dev/md0: 12.0TB
Sector size (logical/physical): 512B/4096B
Partition Table: gpt
1 1049kB 12.0TB 12.0TB xfs Linux filesystem
When I try xfs_growfs, however, nothing changes:
diskfarm:root:10:~> df -kh /mnt/4Traid5md/
Filesystem Size Used Avail Use% Mounted on
/dev/md0p1 7.3T 6.5T 863G 89% /mnt/4Traid5md
diskfarm:root:10:~> xfs_growfs -d /mnt/4Traid5md/
meta-data=/dev/md0p1 isize=256 agcount=32, agsize=61043072 blks
= sectsz=4096 attr=2, projid32bit=1
= crc=0 finobt=0
data = bsize=4096 blocks=1953377275, imaxpct=5
= sunit=128 swidth=256 blks
naming =version 2 bsize=4096 ascii-ci=0 ftype=0
log =internal bsize=4096 blocks=521728, version=2
= sectsz=4096 sunit=1 blks, lazy-count=1
realtime =none extsz=4096 blocks=0, rtextents=0
data size unchanged, skipping
diskfarm:root:10:~> df -kh /mnt/4Traid5md/
Filesystem Size Used Avail Use% Mounted on
/dev/md0p1 7.3T 6.5T 863G 89% /mnt/4Traid5md
I've searched high and low and haven't found any indication of why I
shouldn't be able to grow as long as the partition is large enough, so
now it's time to dive into the mailing list :-)
Please bcc: me on your replies since I am not subscribed. I promise to
follow up with my ongoing results :-)
TIA & HAND
:-D

Did parted tell the kernel to reread the partition table?
blockdev --getsz /dev/md0p1 will tell us the kernel's view of how big
md0p1 is right now.
unmount, blockdev --rereadpt /dev/md0, try again(?)

Well, I thought that it did, since I kept seeing the new size plus saw
the larger partition, but I admit that I don't know, because ...

WOO HOO! That's awesome :-) Thanks so much!
Now I'm off to read the blockdev man pages to figure out what magick thou
has given mee, good sirrah!
