Re: kern/53350: fill up a malloc md-disk on 5.1-R causes panic
I get the same thing on a 1G machine when trying to use a 768 M ramdisk when
the ramdisk is only 25% full.
It never fails at exactly the same place, but always within a minute or two
and it never gets anywhere close to filling up the md-disk.
In my case I was creating the 768 meg malloc disc and trying to copy
/usr/src into it.
initially I tried a couple times with midnight commander, and after that
crashed twice, I tried just using tar
mdconfig -a -t malloc -s 768m
newfs -U /dev/md0
mount /dev/md0 /md0
cd /usr/src ;tar cvf - * |(cd /md0 ;tar xvf - )
/usr/src is only about 350 megs so it should fit easy, but just in case some
difference in block sizes cause the same data to take up mor room on md0
than it does on the hard drive, I watched df in another console while it was
copying.
repeatedly looking at df in another consle showed the disk only reaching
about 25% full at the time of kernel panic.
I got some different messages each time
one time I just got this line repeated scrolling up the console untill I
decided to power off:
initiate_write_filepage: already started
the last time I got this:
panic: kmem_malloc(4096) kmem_map too small: 275251200 total allocated
syncing disks, buffers remaining... 7095
panic: initiate_write_inodeblock_ufs2: already started
This is the 5.1 that is on the 5.1 iso as of about Nov/03/2003
