Problem installing NetBSD 7.1.1 on my SparcStation 5

Hi,

I'm trying to install NetBSD 7.1.1 on my old SparcStation 5. CD-ROM drive seems to be defective so I have no choice but to netboot it. I am already using a Solaris 10 x86 to netboot my Solaris server so I used it to also netboot NetBSD.

Netbooting seems to be working. I mean, it load everything and I get to the installation menu.The only problem I have at the beginning of the install. The installer try to partition, format and mount the disk. I alway get this error :

mount_ffs: Warnning realpth /dev/sd0a: File too large
mount_ffs:: /dev/sd0a on /targetroot: File too large

So I tried to get to the shell to mannually mount the disk but when I simply run a "ls -lh" in /dev I get the same eroor message for lot of devices :

ls: altmem0a: File too large
ls: altmem0b: File too large
ls: altmem0c: File too large
ls: altmem0d: File too large
ls: altmem0e: File too large
ls: altmem0f: File too large
ls: altmem0g: File too large
ls: altmem0h: File too large
ls: altmem1a: File too large
ls: altmem1b: File too large

And it goes the same for all these devices :

altmem0a
altmem1a
ccd0a
ccd1a
ccd2a
ccd3a
cd0a
fd0a
raid0a
raid1a
raid2a
raid3a
raid4a
raid5a
raid6a
raid7a
sd0a
sd1a
sd2a
sd3a
sd4a
xd0a
xd1a
xd2a
xd3a

I first thought it might be because it was mounted via NFSv2 however I verified that point :

soqc1-jumpstart1:/srv/netbsd/netboot on / type nfs (root file system, fsid: 0xb01/0x70b, reads: sync 0 async 0, writes: sync 0 async 0, [nfs: addr=192.168.1.70, port=2049, addrlen=16, sotype=2, proto=0, fhsize=0, flags=0x8280<noconn,nfsv3,resvport>, wsize=8192, rsize=8192, readdirsize=8192, timeo=300, retrans=10, maxgrouplist=16, readahead=2, leaseterm=0, deadthresh=9])
mfs:7 on /tmp type mfs (synchronous, local, fsid: 0xff01/0x78b, reads: sync 58 async 0, writes: sync 18 async 18, [mfs: base=0xedefc000, size=1048576])

I also created a 2.2 Gb file using "dd if=/dev/zero of=zero.txt" and there is no problem when I run a "ls -lh" in the directory where it is.

Does anybody ever had this weird problem ?
