I recently upgraded my pc532 box from NetBSD 1.1 to 1.3.
The box has three SCSI disks. These worked fine
under 1.1. Under 1.3, the third disk (sd2) behaves
oddly:
- writing a file on a mounted filesystem (FFS)
causes the entire contents of that directory to
become invisable, until the filesystem is unmounted
and remounted. The data written then shows up.
- writing to a partition using the raw device fails:
machup # dd if=/dev/zero of=/dev/sd2a bs=8k count=1
1+0 records in
1+0 records out
8192 bytes transferred in 1 secs (8192 bytes/sec)
machup # dd if=/dev/zero of=/dev/rsd2a bs=8k count=1
dd: /dev/rsd2a: end of device
1+0 records in
0+0 records out
0 bytes transferred in 1 secs (0 bytes/sec)
machup #
In this case, the data written does not make it
out to the disk.
The sd0 and sd1 disks work fine. The /dev entries appear to
be correct. I've tried zeroing out the first part of the disk
and then writing a fresh disklabel. I've tried building a kernel
with explicit entries for sd0, sd1 and sd2 rather than depending
on wildcarding.
