zfs, raidz and compression?
807557Jan 25 2008 — edited Mar 5 2009Running SXDE (snv_70) for a file server, and I'm new to Solaris.
I created a four drive raidz array:
zpool create pool raidz c0d0 c0d1 c1d0 c1d1
then an extra file system on that:
zfs create -o mountpoint=/export/data pool/data
After adding a bit of data (200GB or so), i figured that compression would in fact be a good idea:
zfs set compression=on pool/data
So far so good, "zfs get all" reports compression to be active. Now for the problem: After adding another 300GB of uncompressed .tif and .bin/.cue files, compression ratio is still at 1.00, indicating that no compression has taken place. Where did I go wrong? Anything I can do to get compression back after the cause for the problem has been fixed? All the data has been copied across a network, through the Samba service - set up according to instructions found in these forums.
