Spliting a partition
- Thread starter bigscouse
- Start date
It's as simple as creating the new partition, mounting it as "/vol01", and then deciding what to move across from "/opt". You may need to provide symbolic links back to the original "/opt" location for the directories you move.<br><br>Don't forget to take backups before doing anything, though

Thanks AndyBo,<br><br> I have already run tar on opt, put an entry in vfstab, and unmounted opt. Now I need to know how to create the new partition. <p>Ged Jones<br><a href=mailto:gedejones@hotmail.com>gedejones@hotmail.com</a><br><a href= > </a><br>
Ah... this bit is relatively easy <br><br>Assuming you want to create a UFS file system, run:<br><FONT FACE=monospace><br>newfs /dev/rdsk/c?t?d?s?<br></font><br>Of course, you want to replace the question marks with the appropriate values... This will prompt you for confirmation, and then create the new file system for you.<br><br>For more details, see "man newfs" and "man mkfs_ufs".<br><br>Hope that helps. <p> <br><a href=mailto: > </a><br><a href= > </a><br>--<br>

I had tried that but got the answer "preposterous size 0 sectors." <br><br>I need to reallocate the space on /opt between /opt and the new partition, that is the bit that is phasing me.<br><br>Thanks again for your help. <p>Ged Jones<br><a href=mailto:gedejones@hotmail.com>gedejones@hotmail.com</a><br><a href= > </a><br>
Just so I'm clear on things, you have /opt that contains an amount of data. You have created a new partition that needs a file system (known as /vol01) creating on it. Once you have /vol01, you want to move some things off /opt onto /vol01. Do you also want to change the current size of /opt so that it is smaller, and then allocate the space that has been freed up to /vol01? (All of this assumes that /opt has been set up on it's own disk partition...)<br><br>Assuming you have the new parition created, you could try running <FONT FACE=monospace>mkfs</font> directly, instead of via <FONT FACE=monospace>newfs</font>:<br><FONT FACE=monospace><br>mkfs -F ufs /dev/rdsk/c?t?d?s? <i>size_of_partition</i><br></font><br>The "size_of_partition" value is specified as the number of sectors in the partition. You should have this information from when you created the partition. If not, then "<FONT FACE=monospace>prtvtoc /dev/rdsk/c?t?d?s2</font>" will show it.<br><br>Post back if you need to resize the "/opt" partition. That could start to get a bit tricky, depending upon how much unallocated disk you have elsewhere on the system. <p> <br><a href=mailto: > </a><br><a href= > </a><br>--<br>

There is the problem, I have not vreated /vol01 as such yet.<br>/opt is 4.5 gig loads of space on /dev/rdsk/c0t0d0s5 and I need to set up /vol01 on c0t0d0s6 using 2 gig from /opt.<br>I have been using format but must be doing something wrong. <p>Ged Jones<br><a href=mailto:gedejones@hotmail.com>gedejones@hotmail.com</a><br><a href= > </a><br>

Sorted,<br><br>Thanks for your assistance Andy, <br>My problem was when using format I did not use the label option to write the changes to disc.<br><br> <p>Ged Jones<br><a href=mailto:gedejones@hotmail.com>gedejones@hotmail.com</a><br><a href= > </a><br>
