zfs discuss - Sep 2009 - Changing the recordsize while replacing a disk

Hello,

Quick question:

I have changed the recordsize of an existing file system and I would 
like to do the conversion while the file system is online.

Will a disk replacement change the recordsize of the existing blocks?

My idea is to issue a "zpool replace <mypool> <old_disk>
<new_disk>

Will this work?

Thanks in advance,

Javi

No it won''t.

However all new files which are created will be using a new recordsize.
If you want the old files''s recordsize to be changed you will have to 
copy them and remove old version.
