Back to the 3Tb:
Today I built a stripe set of 7*4.3Gb. I have this nice little raidbox
sitting in my lab at work and wanted to give it a try with a big filesystem.
So, I hooked it up to a spare 486/33 with a Adaptec 1740. Used 2.1R
No luck there, it looks like the ahb driver does not 'see' it on boot.
Second attempt, hooked it up to a Adaptec 1542B that also serves the boot
disk. Found it!
OK, disklabel and newfs. 1 hour and 20 minutes later I had this 28+ Gb
filesystem... Only problem sofar: 'df' reports a negative 'avail' number.
Percentage is also -0% (noi typo). I'll try to find out why this happens.
Any known problems with disks this big?
When it comes to big 'disks' I can currently make them up to 14*4.3Gbyte
in size... (Need to steal most of the 4.3Gb disks from my colleagues
but what the h*k)
Wilko
