Description of problem: First, there are NO /dev/ram[0-9] devices upon install. Now, MAKEDEV ram9 can be used to make say ram9 and this results in: # ls -lZ /dev/ram9 brw-rw-rw-. root disk system_u:object_r:fixed_disk_device_t:s0 /dev/ram9 But if mkfs -t ext2 /dev/ram9 is attempted, then this results in: mkfs.ext2: No such device or address while trying to determine filesystem size Now, the kernel config file does not compile it statically in the kernel - instead, it sets it as a module (where as previous releases would set it to "=y"). /boot/config-3.1.1-1.fc16.x86_64 has: CONFIG_BLK_DEV_RAM=m CONFIG_BLK_DEV_RAM_COUNT=16 CONFIG_BLK_DEV_RAM_SIZE=16384 However, its module should load the first time the device is accessed. Floyd, Version-Release number of selected component (if applicable): How reproducible: always Steps to Reproduce: 1.use makedev to create a /dev/ram# device. 2.Try to mk a fs onto - fails. 3. Actual results: always fails Expected results: succeeds in fc15, 13 12 etc. Additional info:
It looks like we still have the old name in our configuration files. Try changing alias block-major-1-* rd to alias block-major-1-* brd in /etc/modprobe.d/dist.conf. That should make it auto-load. You can also change the default config options by adding a line to some file in /etc/modprobe.d like this: options brd rd_nr=X rd_size=Y max_part=Z where X is the number of ramdisks you want, Y is their size, and Z is the maximum partitions per disk.
Did those suggestions work?
(In reply to comment #2) > Did those suggestions work? Yes, the first was tried, and it worked. Thanks very much. Floyd,
Changing to correct email address. Apologies for the delay.
