[SunHELP] »Ø¸´: »Ø¸´: [SunHELP] capacity of filesystem /

[Sizheng Zhu]

Hi Jeremy,

(1)
The file I mentioned is "sn.l" and locates in /dev/prom, not in /proc. Its
size has been increasing quickly:
    /dev/prom/sn.l    93206340    Sep 23 16:37
    /dev/prom/sn.l    93375194    Sep 24 08:38

Some of its contents are as follows ( I have replaced some information with
xxx):

I have no idea on this garbage file, but it does occupies the space of the
filesystem /.

Could you please explain "delete all the file in /dev/rmt and recreate them
using ..." in detail ?

Best regars,
