Greetings,
In short, I have a 1TB USB HDD that is formated Ext2. I used it to
copy all my data off my old RH system before blowing it away to install
OpenSolaris.
I have OpenSolaris (snv_101b) installed and running. I installed
FSWfsmisc and FSWpart. I can mount my external USB drive successfully
using -
mount -F ext2fs /dev/rdsk/c8t0d0p0 /ExtMovies
I can list out the directory without any issues. I issued the cp
command to copy the ext2 filesystem to my ZFS RAIDZ Pool filesystem. I
left it running all night since I have ~700GB of data to move. However,
the morning revealed that the large files did not completely copy. It
appears they copied 2^31 bytes and then ended with an error "Invalid
Argument." Here is the data from a single file copy :
r...@opensolaris:~# cp /ExtMovies/movies/After_the_Sunset.VOB
/data/movies -v
`/ExtMovies/movies/After_the_Sunset.VOB' ->
`/data/movies/After_the_Sunset.VOB'
cp: reading `/ExtMovies/movies/After_the_Sunset.VOB': Invalid argument
When you do the ls command of the ext2 filesystem it show the proper
number of bytes - 3,766,013,952 bytes.
r...@opensolaris:~# ls -l /ExtMovies/movies/After_the_Sunset.VOB
-rwxr--r-- 1 root root 3766013952 2007-12-26 15:55
/ExtMovies/movies/After_the_Sunset.VOB
Here is the ls command of the resulting cp that failed :
r...@opensolaris:~# ls -l /data/movies/After_the_Sunset.VOB
-rwxr--r-- 1 root root 2147352576 2009-06-30 10:10
/data/movies/After_the_Sunset.VOB
My guess is that there is a limitation in the FSWfsmisc
implementation that does not account for large files. Could it be the
NFSv2 restriction since this is really a loopback type implementation in
userland?
Is there a way around this problem? Is there a "LargeFileSupport"
bit or mode that can be set to support these large files? Any help
would be deeply appreciated as I have spent a lot of time going through
all the Forums looking for this answer.
Thanks!
RB
