No hard disk crash today (I'm just disabling the DMA )-" ) However, I've tried to make small reiserfs partitions, and was annoyed at the journal taking a significant size of the disk: 32MB is 50% of my 64MB /boot partition, and 40% of the whole of my server's 80MB harddisk. I saw that mkreiserfs had an option -s to select the size of the journal, and tried to use it to make a 4MB journal: mkreiserfs -s 1024 /dev/hdc1 However, whereas mkreiserfs didn't complain, the resulting partition was unmountable by linux. In the syslogs, the kernel complains: read_super_block: can't find a reiserfs filesystem on (dev 16:01, block 128= , size 512) read_super_block: can't find a reiserfs filesystem on (dev 16:01, block 16,= size 512) I there a way to make a reiserfs partition with a small journal? 32MB is really a waste, on some partitions. Would a small kernel patch do it? In any case, I think that it is a bug that mkreiserfs doesn't check the consistency of its parameters with what the kernel is able to handle. PS: I'm using debian's reiserfsprogs 1:3.6.4-2 and linux kernel 2.4.20. Cheers!
