<div>U may reduce LV size and get some free space but that still will be lying on PV and there is no pvreduce (afaik).</div> <div> </div> <div>So, I think (I may be wrong), U are out of luck. Get your luck back, have same temporary storage for your data to change the size or convert PV. </div> <div> </div> <div>UC, LVM is good for multi-partitions and multi-disks, everything in multiples. That's the playground for LVM.</div> <div>When U (re)start for FC4 or FC5, have your linux space on multiple PV's.</div> <div>I will suggest utilize all 4 primary partitions,</div> <div>1. boot, 2. dual boot (if required) else PV and 3.& 4 also PV's. Swap goes in LVM.</div> <div>LVM can make them look like one or as desired partitions (LV's), which U can change as per your requirements, even for dual boot.</div> <div> </div> <div> Hard luck with "auto partition" - it is good for itself! smart fellow not caring for our moods.<br><br> </div><br><br> <div><span class="gmail_quote">On 12/12/05, <b class="gmail_sendername">Andrey Subbotin</b> <<a onclick="return top.js.OpenExtLink(window,event,this)" href="mailto:eploko@gmail.com" target="_blank">eploko@gmail.com</a> > wrote:</span> <blockquote class="gmail_quote" style="PADDING-LEFT: 1ex; MARGIN: 0px 0px 0px 0.8ex; BORDER-LEFT: #ccc 1px solid">Hello all.<br><br>I've got a 200GB HD partitioned automatically during Fedora Core 4 setup. That is the disk carries 2 partitions where the first one (/dev/sda1) is ext3 mounted as /boot and the second one (/dev/sda2) is an LVM. <br><br>That is all clear and fancy but the problem is I'm faced with the fact I need to migrate the HD to Ext2 FS, so I could convert it to FAT32 later, so I could access it from a copy of the Windows OS I happen to boot recently to do some work. The LVM on /dev/sda2 is full of data I need to save and the problem is I don't have a spare HD to temporarily copy all those 200GB to. <br><br>If I had a spare HD I would eventually mount it, make a new Ext2 partition on it and then copy all the data from the LogicalVolume to the new partition. Then I would fire up fdisk and kill the LVM, thus freeing the space on the drive. Then, moving the data back to the first HD would be a snap. But without a spare disk I face a real challenge. <br><br>My initial idea was to reduce the FS inside the LogicalVolume (it has ~40GB free of space) and then reduce the size of the LogicalVolume and then reduce the PhysicalVolume /dev/sda2 by the freed number of cylinders. Then, I would create an ext2 partition over the freed cylinders and move some files from the LogicalVolume onto it. Then I thought I would repeat the process several times effectively migrating my data from the ever-shrinking LVM to the ever-growing plain Ext2 FS. <br><br>The problem is I have little idea how I can shrink an LVM partition on /dev/sda2. And there seem to be very little information on this on the net.<br><br>So far, I have lvreduce'd the FS inside the LogicalVolume and the LogicalVolume itselft to 35700000 4k blocks. Now, how do I redeuce the number of cyllinders occupied by the LVM on /dev/sda? <br><br>I would really apreciate any help or ideas.<br>Thanks a lot in advance.<br><br>--<br>See you,<br>Andrey<br><br>ICQ UIN: 114087545<br>Journal: <a onclick="return top.js.OpenExtLink(window,event,this)" href="http://www.livejournal.com/users/e_ploko/" target="_blank"> http://www.livejournal.com/users/e_ploko/ </a><br><br>_______________________________________________<br>linux-lvm mailing list<br><a onclick="return top.js.OpenExtLink(window,event,this)" href="mailto:linux-lvm@redhat.com" target="_blank"> linux-lvm@redhat.com</a><br><a onclick="return top.js.OpenExtLink(window,event,this)" href="https://www.redhat.com/mailman/listinfo/linux-lvm" target="_blank">https://www.redhat.com/mailman/listinfo/linux-lvm </a><br>read the LVM HOW-TO at <a onclick="return top.js.OpenExtLink(window,event,this)" href="http://tldp.org/HOWTO/LVM-HOWTO/" target="_blank">http://tldp.org/HOWTO/LVM-HOWTO/</a><br></blockquote></div><br><br clear="all"><br>-- <br>Anil Kumar Shrama
