Alright, here’s how – usfsdump – How To Backup Solaris\/Linux Root Filesystem. use ufsdump<\/p>\n

Say for example you have this:<\/p>\n

$ df -k \/
\nFilesystem kbytes used avail capacity Mounted on
\n\/dev\/dsk\/c0t0d0s0 673951 415497 197799 68% \/
\n$ df -k \/CMS
\nFilesystem kbytes used avail capacity Mounted on
\n\/dev\/dsk\/c0t8d0s0 35009161 32305691 2353379 94% \/CMS
\n$ <\/p>\n

yeah, the \/CMS file system is almost full, but I think it can still accomodate a 674MB root filesystem from the slice \/dev\/dsk\/c0t0d0s0, right?<\/p>\n

Anyway, not sure if the 2GM limit<\/a> is applicable to Solaris 8,9 or 10 but since this example is less than 1GB, we are ok to proceed.<\/p>\n

myserver# cd \/CMS
\nmyserver# ufsdump -f dumpfile \/dev\/dsk\/c0t0d0s0

ufsrestore should do the trick in recovering the system.. hopefully<\/p>\n","protected":false},"excerpt":{"rendered":"
