Re: RE: why jffs2 complain no space left on device while there is some space left ?
Dear Spencer Shanson:
thank u very much, but perhaps your solution have no effects to me, the number of sectors for each partion is more than 8 now, and sectors are contiguous, following are the partions info, and each sector size is 64k, so the sector number of partion '/dev/mtdblock2' is 63 sectors, do you have any suggestion? thanks a lot.
Filesystem 1k-blocks Used Available Use% Mounted on
/dev/mtdblock2 4032 3972 60 99% /
/dev/mtdblock3 2880 2860 20 99% /mnt/mtd3
