Interesting. I've not had that problem, but I've never resized a reiserfs |
16 |
partition, either. I'd be particularly worried about resizing it smaller, |
17 |
due to the way reiserfs works. I know the resizer is supposed to handle |
18 |
it, but ... |
19 |
|
20 |
I've always created a new partition, done a mkreiserfs, then copied |
21 |
everything from the old to the new. (There's no reason to move, if the |
22 |
next step is simply going to be to erase that partition anyway. That |
23 |
saves the delete step of the move.) |
24 |
|
25 |
As for other parameters of a reiserfs volume, I've had no issues with |
26 |
non-standard journal sizes -- I have both larger and smaller journal sizes |
27 |
than the default on my system, but I DID have issues with non-standard |
28 |
block sizes. Some files that worked just fine on a 4096-byte standard |
29 |
block layout had issues when moved to an 8192-byte block reiserfs |
30 |
partition. Most stuff worked fine, but some stuff just wouldn't. Putting |
31 |
it back on a 4096-byte block partition, everything was fine again. The |
32 |
only thing I could figure was maybe the blocksize code didn't get ported |
33 |
to 64-bit correctly, and while the default size works fine as it has had |
34 |
lots of testing, the same can't be said about other block sizes. (The |
35 |
partition I was trying this on was primarily large sized files, so I |
36 |
thought the 8192-byte blocks would be better, especially since tail |
37 |
packing means no wasted space anyway.) So... I'll now change the journal |
38 |
size as I deem appropriate for a partition as I'm doing the initial |
39 |
mkreiserfs, but I leave blocksize alone. That's one less parameter to |
40 |
have to track, anyway. =8^) |
