ext2 (for removable media)
I am trying to figure out the fastest way to get data off of our embedded system post-flight and into the hands of the
scientists for data analysis. We expect to be acquiring ~40GB per flight, and it needs to get to three different systems
running both Linux and Windows for data analysis. Having done the math, I figured the fastest method would be to use
eSATA to write to an external disk, then move the disk to the first target system and repeat 3 times. Looking at the
matrix of supported filesystems, it looks like ext2 is the only one that is both writable under QNX and readable under
both Linux and Windows.
I've got the drive, I formatted it with ext2 on a CentOS 6.4 system, brought it over to QNX, see that the partition
shows up (/dev/umass0t131), but:
# mount -T ext2 /dev/umass0t131 /fs/T1
mount: Can't mount /fs/T1 (type ext2)
mount: Possible reason: Invalid argument
Any ideas what's going on?
Any suggestions?
