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^) |
