Hi,
Hello.
It's been a while since I last tried reiser4, and having just looked
at the wiki, I couldn't find any info at all on the cryptocompress
plugin and tail packing options at mkfs time specifically relating to
reiser4.
mkfs.reiser4 -l:
compression modes (works "per file"):
"latt" (id:0x1 type:0xd) ['Check on dynamic lattice'
compression mode plugin.]
If logical cluster in incompressible, then switch compression off and
check every
K-th cluster, where K dynamically increased to 32 on every non-success
after
compression. If cluster is compressible, than K is set back to 1, etc..
"ultim" (id:0x2 type:0xd) ['Check ultimately' compression
mode plugin.]
Switch compression off forever after the first case of non-success.
"force" (id:0x3 type:0xd) ['Compress evrything'
compression mode plugin.]
Force to compress everything.
"conv" (id:0x4 type:0xd) ['Convert to extent' compression
mode plugin.]
If the first logical cluster of the file is incompressible, then
switch compression off forever.
Sorry, this is not everything. Here should also go "otherwise switch to
"latt" mode
(see above)".
So not everything is bad for media-files in this mode.
