Solaris Commands Interview Question:

How to convert a volume from gen to fsgen? why
should you do that?

Submitted by: Administrator

1) #vxprint -g dgname -rhmvps filename >
filename.vxoutput
2) open the file simplevol.vxout using your fav editor and
change the use_type field alone from gen to fsgen.
3. Save the file. make sure you edit the use_type field
alone…
4. Umount the filesystem; umount /simplevol
5. stop the volume ; vxvol -g dgname stop simplevol
6. remove the volume ; vxedit -g dgname -rf rm simplevol
7. using vxmake rebuild the volume from the saved file ;
vxmake -g dgname -d simplevol.vxout
8. check the vxprint out; vxprint -g dgname -hrt ; check
for the usage type; it would be fsgen
9. start the volume; vxvol -g dgname start simplevol
10. do a fsck for the volume; fsck -
y /dev/vx/rdsk/dgname/simplevol
11. mount the filesystem ; mount /simplevol
gen assumes a volume does not contain filesystem and fsgen
assumes a volume contains a file system. Vxassist uses
fsgen as default type and vxmake uses gen as default type.
