Someone Told me that i Have the "bug 193 in bugzilla". But how do I handle the Bug? How can I Read the data out of the partition? I had the following things running for a short while: - RedHat 7.1 with all updates. - self-compiled Kernel 2.4.6 with patched lvm 0.9.1_beta7 On my first HD Igave the rest space to hda7 with fdisk and set the partition to "8e" lvm. The I followed the howto at sistina at: file://sistina.com/lvm/doc/lvm_howto/Common_tasks.html - I initalized the Partition: pvcreate /dev/hda7 - I added the partition to a new volume group: vgcreate lvm_volume_01 /dev(hda7 - then o activated the volume group: vgchange -a y lvm_volume_01 - The I put a logical volume on the volume group: lvcrate -L50G -nlvm_lv_01 lvm_volume_01 This logical Volume was then at /dev/lvm_volume_01/lvm_lv_01 and o formated it woith reiserfs an mounted it! Evething runs fine. I copied the old contents of hdb5 and hdc5 of the smaller HDs to this logical volume. on hda7. Then I added deleted the partition on hdc5, made a new one, set it to 8e an added it to the volume group as explained at: file://sistina.com/lvm/doc/lvm_howto/Common_tasks.html pvcreate /dev/hdc5 vgextend lvm_volume_01 lvextend -L30G /dev/lvm_volume_01/lvm_lv_01 resize_reiserfs -f /dev/lvm_volume_01/lvm_lv_01 That was all fine and i could mount the lvm_lv_01 without any problems. The same I then wanted to manage with the thirt HD at hdb5, but then something went wrong?? Resize reiserfs did something but when i wanted to mount the LV it did not work. reiserfs-checks did not found a problem but the mount-binary told my something about a superblock...... Abter a reboot I now have the following: [root@holodeck lvmconf]# pvdisplay /dev/hda7 pvdisplay --- Physical volume --- PV Name /dev/hda7 VG Name lvm_volume_01 PV Size 48.54 GB / NOT usable 1.06 MB [LVM: 169 KB] PV# 1 PV Status available Allocatable yes (but full) Cur LV 1 PE Size (KByte) 4096 Total PE 12425 Free PE 0 Allocated PE 12425 PV UUID cFFBJX-aqxr-P7kU-71OY-pgpX-rvtA-XxVpoc But for /dev/hdb5 and /ev/hdc5 it does not show the same. NOTHING!! And becouse I did not write anything to the volumegroup or logical volume after the added two partition al my data must still be on hda7. But how do I manage to get on it? SHIT! How do I get on my Data at lvm_volume_01 bzw lvm_lv_01. lvm_lv_01 was formated with reiserfs Greetings from Germany from Alex
