My issue is that compression doesn't work, Not sure what "compression=gzip" will give you. I believe you might be safer using "compression=gzip-6" or whichever value you want to use. gzip9 will be pretty slow if that's the default for "gzip". I use lzjb because there isn't much advantage to gzip, at least in my experience, and lzjb is fast. I did some testing and didn't find a big space savings with gzip-6 or gzip-9. % zfs get compressratio NAME PROPERTY VALUE SOURCE raid1 compressratio 1.78x - raid1/BACKUPS/BACULA compressratio 1.83x - -- Dave Robison Sales Solution Architect II FIS Banking Solutions 510/621-2089 (w) 530/518-5194 (c) 510/621-2020 (f) daver@vicor.com david.robison@fisglobal.com _____________ The information contained in this message is proprietary and/or confidential.
