I have a problem with system v filesystems. I have several AT&T unix boxes kicking around, and on SCO Unixware 7.0.1 box. Data is moved via sneakernet (on zip disks) between the machines. The zip disks have are using the system v file system. We would like to bring some Redhat 7.3 machines into the mix. However I'm having some problems with the sysv file system driver on Redhat. I tested it with a Redhat 7.0 machine and it worked fine read and write. However when I tested it with Redhat 7.3 only reading worked.
I'm mounting the zip disks like this mount -t sysv /dev/sda5 /mnt/zip After doing this I just issue a simple mount command and the list of mounted file systems states that /dev/sda5 is mounted read write and is a sysv file system. I can read from the disk fine. However when I attempt to write a file to the disk it states that the cp command couldn't finish because the file system is read only. This happens in Redhat 7.3, in ReadHat 7.0 everything works fine. Did they remove write support for sysv file systems between 2.2 and 2.4?
