Hi Folks,
trying to create filesystems on a couple of 72Gb scsi disks. partitioning of disks goes fine using 'format'. When I try and use newfs I get the error message ' ERROR DETERMINING ALTERNATE SUPERBLOCK LOCATIONS' Tried using fsck to allocate another superblock, but this spouts out a 'BAD MAGIC NUMBER' error. Any advice would be greatly appreciated.
Thats sounds strange. Ive never seen newfs do that.
Fsck only repairs existing file system. So if newfs couldnt create it in the first place, theres nothing for fsck to repair.
You might want to post the output of format.
select the disk.
Then do "p<ret>p<ret>
to print the partition table.
Post the exact newfs command your using
do one thing
send the out put first
let me read the error my self .
try this first and delete the partion if exist
format -e
if you still getting the error post the eror
are all 8 partion you can able to see. hard to say. send the output what you doing.
