Reducing a filesystem

[Haitham Hamad]

I am trying to reduce a hfs filesystem from 2.5G to 2G (used volume is up to 1.7G). Is there a simpler way than recreating the filesystem and bringing a backup. We don't have advanced JFS

[Vikas Khator]

Nop!

Can't think of a reliable and safe way to reduce FS without advance JFS ( also not sure if advance JFS would allow you to reduce hfs filesystem)

[A. Clay Stephenson]

In an hfs filesystem this can't be done.

Just went through this myself on a 10.20 box and I had to recreate and restore. Sorry, hope this helps.

Backup your file system,umount it,lvreduce -L totalMb /dev/vgxx/lvolxx,mount and restore.

[Thierry Poels_1 · Accepted solution]

lvreduce on a hfs filsystem? NO WAY

copy, backup or move your data, drop the filesystem, an recreate the (vxfs ;) filesystem.

good luck,
Thierry.
