Converter program from V3 to V4 ?

Converter program from V3 to V4 ?

[Thomas Graham]

reiserfs 4 will be release soon, I got almost 90GB data on a HD that is
using reiserfs3, how could I install v4 on this HD ? would it have a
converter program to concert from V3 to V4 ? Thanks.

You should have a backup which you can use to restore your data onto
ReiserFS v4 once that's released. Personally, I'd be chary about going
ReiserFS v4 short after the release. It took ReiserFS v3 a long time
(years) to mature; and although I expect ReiserFS v4 to take not that
long, you shouldn't trust important data to a new file system driver
from the first day. Start with recoverable data first.

The converter program is called tar.  Maybe someday we will write a 
script to resize partitions incrementally as we copy data from one 
partition to another....

Remember that filesystems take many years to stabilize to where V3 is 
now, and V4 will be flaky when it first ships.  Every bug we know how to 
find will be fixed, but real users find bugs test suites don't.

There is the intersting approach called convertfs.
