e2c4399e28 More precise disk usage time 
When we wait, we now count the time for all the waiting disks,
and not only for the first one that finish.

cbf2040b89 Add mutex protection at the filesystem structure 
In sync we need to modify the filesystem, like to call
fs_deallocate(). We need then proper protection.
This also removes the need of multiple fs_last cached value.

fa3f17ac20 Restore defalt scrub percentage to 8% 
This is like the previous 8.1 version, even if the documented
one in the doc was 12%, the real one was 1/12==8%.

40265401d3 Rename the --percentage option to --plan 
The old --percentage is still supported, but not documented anymore.

1917814d2d Restore the default scrub behaviour of the previous version 
If the user like to scrub new blocks, he can now use the -p new
option, and then call again scrub with a percentage to scrub the
old blocks.

Scrubbing old and new blocks are two different operations, and make
sense to keep them separated. Mixing them could instead raise
problematic issues, like not being able to predict the time required
for a full scrub cycle, as it depends also on the amount of synced
data.
 2015-11-09 23:34:41 +01:00

7f17d667e6 Change the default scrub percentage to 15% 
This is done to take into account that now
synced blocks are scrubbed with priority.

9a5f30cd32 Add a new justsynced info bit to position 
The value 0 means that the block is scrubbed, and it allows
an easy conversion of past content files.
Note that past versions ignore this info when using binary
content files, then we don't increase the version of the format.

c8edf2f002 In scrub don't check the inode to verify if the file is synced. 
On filesystem without persistent inode, they can be different from
one run to another.
In sync they are automatically adjusted, but not in scrub.
