SUNOS 4.1.3 Tape Restore failed
Hi,
I am trying to restore file systems on SparcStation 20 (SunOS 4.1.3) from a dump tape (made from another SPARCStation20 SunOS 4.1.3).
1) I booted from solaris 1.1.1 CDrom
2) Install Mini OS
3) Restart from the mini OS.
4) newfs /dev/rsd0a
5) mkdir /tmpa
8) mount /dev/sd0a /tmpa
9) cd /tmpa
10) restore -rf /dev/nrst0
It did restore the / file system to it. Then I started to restore /var
1) umount /tmpa
2) newfs /dev/rsd0d
3) mkdir /tmpd
3) mount /dev/sd0d /tmpd
4) cd /tmpd
5) restore -rf /dev/nrst0
It did restore the /var file system to it. Then I started to restore /usr
1) umount /tmpd
2) newfs /dev/rsd0g
3) mkdir /tmpg
3) mount /dev/sd0g /tmpg
4) cd /tmpg
5) restore -rf /dev/nrst0
Unfortunately, it didn't work. Instead, it displayed the following error
message,
/: write failed, file system is full
/: file system full
....
...
expected file nnnnnn, got mmmmmmm
expected file xxxxxx, got yyyyyyy
.......
.......
The /usr partition is using only 528MB on a working SPARCStation 20. I made a 1405MB /dev/sd0g partition in a new SPARC 20. I don't know, why it giving me error message that file system is full.
Also, / is 79MB and /var is 150 MB on working SPARC20 and I made / 150MB and /var 155MB on new SPARC 20.
First, I thought that the dump tape is bad, so I put a crossover Ethernet cable between working SPARC20 and new SPARC20.
Then, on new SPARC20
boot from cdrom
install mini root
newfs /dev/rsd0g
mount /dev/sd0g /tmpg
cd /tmpg
rsh -n hostname dump 0f - /dev/rsd0g | restore rf -
I got same error messages.
I will be really appreciated if you can help me.
Thanks,
John

If you want to use NFS, you need to let the NFS client has root access to
the filesystem, you need to make sure both NFS server and client knows
each other, defined in /etc/hosts, or NIS/NIS+, or DNS etc, then
share it like:
share -F nfs -o rw=clientbox,root=clientbo
tar is not the tool for the job, it can't handle special files. you can use
cpio:
eg:
cd /source-dir
find . -print | cpio -oacv | (cd /target-dir ; cpio -icdmuv )
man cpio

Good luck!

Yes, I tried /usr partition to 750MB; however, I got same result.
Yes, I can go to "format". My drives is 2 GB drives. I allocated enough disk space for the partition.
I was searching through internet yesterday, and some body has similar problem with restoring only /usr partition. He wrote solution which I don't understand:
"*************************
Their replies are quite helpful. All of them think that my / file system of the mini root is full because 'restore' generate some temporary files.
Actually the two files are /tmp/rstdir*, /tmp/rstmode*.
The strange point is that these two files are not big, only about 1M(maybe 10M?). I am sure the file system is NOT full because I installed the mini root on a 500M partition, you know, the mini root won't take too many spaces. I did expand my swap space which is installed mini root, but it didn't help. Anyway, after I delete it, i am able to restore other file systems.
In the fact, I solved my problem in another way. I restore the file systems in another computer, share it, and then "tar" them to this host. This solutions has a strange point too. When I used 'tar' to copies files from the remote host, it displayed some warnings that,
./etc/restore: permission denied
./etc/in.uucpd: permission denied
..... (some other files, permission denied too).
I checked the files permission, the permission mode is 400. So it is not readable from NFS. But after my system is recovered, i went to /usr/etc/ and the files ARE there anyway!

If you know this solution, please help me.
