I've tried several things with no success. anaconda _almost_ has all the necessary code for setting the physical extent size. The code is there and the setting is passed around, however the value is hard coded to 4096 and can't be set from the ks.cfg file. Here's my %pre hack for adding stripe options to lvcreate by bind mounting a script over the executable: ######################################################################## cp /usr/sbin/lvcreate /tmp/lvcreate.bin cat > /tmp/lvcreate <<EOF #!/bin/sh exec /tmp/lvcreate.bin -i 2 -I 512 \$@ EOF chmod +x /tmp/lvcreate mount /tmp/lvcreate /usr/sbin/lvcreate -o bind ######################################################################## Now, you'd need to wrap vgcreate instead of lvcreate, and since anaconda already passes the "-s" option, you'll need to have a script that checks the options and changes the "-s" option to your desired setting. Something like (untested!): ######################################################################## cp /usr/sbin/vgcreate /tmp/vgcreate.bin cat > /tmp/vgcreate <<EOF #!/bin/sh pvsize=16M opts="" got_s=0 for opt in \$@; do if [ \$got_s = 1 ]; then opt=\$pvsize got_s=2 fi case \$opt in -s*) if [ \$opt = -s ]; then got_s=1 else opt=-s\$pvsize got_s=2 fi ;; esac opts="\$opts \$opt" done if [ \$got_s = 0 ]; then opts="-s \$pvsize \$opts" fi exec /tmp/vgcreate.bin \$opts EOF chmod +x /tmp/vgcreate mount /tmp/vgcreate /usr/sbin/vgcreate -o bind ######################################################################## This should handle any case of "-s4096", "-s 4096", or no -s option at all. Put that whole chunk in your ks.cfg and just change the "pvsize=16M" line to your desired size. Let me know if it works! :-) -- Chris Adams <cmadams@xxxxxxxxxx> Systems and Network Administrator - HiWAAY Internet Services I don't speak for anybody but myself - that's enough trouble.
