GJournal MUST be run before NewFS, especially on one provider, this should be clearly stated in NewFS manual, before hotshots like me first create the fs and then want the journal, please update. 2. Is it possible to automaticaly create journal by NewFS when -J flag is set? 3. Is it possible to add journal to existing partition (partition and journal are on the same provider) without loosing data on that partition? Gjournal warns that running label -f will destroy the data... 4. When I want to use data and journal on one partiton partition.journal appears after I create a label with gjournal. Why do I mount partition.journal not the partition?? Isn't the journal something that makes data partition to work aka backend? Isn't the journal a metadata that keeps the record of files, if so why do I mount this metadata, this looks odd. 5. In my 9.1-RC3 I see no .journal device for /partition - does it mean that journal is not created by default?? Does bsdinstall remember to first greate gjournal? Any hints welcome :-) Tomek -- CeDeROM, SQ7MHZ, http://www.tomek.cedro.info
