-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Apologies for mailing out of the blue but I'm not sure how to go about this. I'm using the LVM software, very nice it is too :-) but I'm having a couple of issues and I was wondering if they were bugs or if I was using the software incorrectly. If there is another person I should be reporting this to, please let me know 1/ pvcreate cannot use whole disks as referred to in the man pages. pvcreate /dev/hde reports that the partition table exists, this was removed using the dd command; dd if/dev/zero of/dev/hde bs=512k count=1 I can't change the partition table to have 8e because there is not one there so I got round it by createing one single partition for the whole disk and modifying that partition to use Linux LVM. see below. # fdisk -l /dev/hde Disk /dev/hde: 16 heads, 63 sectors, 38792 cylinders Units = cylinders of 1008 * 512 bytes Device Boot Start End Blocks Id System /dev/hde1 1 38792 19551136+ 8e Linux LVM This is the same with different type of disk, I only tested with IDE disks if that actually makes a difference. 2/ I have modified a logical volume to be read only and deactivated it but when using lvchange to reactivate, it won't work. # lvdisplay /dev/vgdata/oracle - --- Logical volume --- LV Name /dev/vgdata/oracle VG Name vgdata LV Write Access read only LV Status NOT available LV # 4 # open 0 LV Size 1 GB Current LE 256 Allocated LE 256 Allocation next free Read ahead sectors 120 Block device 58:4 # lvchange -v -a y /dev/vgdata/oracle lvchange -- locking logical volume manager lvchange -- checking logical volume name lvchange -- checking volume group existence lvchange -- checking for active volume group "vgdata" lvchange -- reading volume group data of "vgdata" from disk(s) lvchange -- checking consistency of "vgdata" lvchange -- checking logical volume "/dev/vgdata/oracle" existence lvchange -- getting index of logical volume "/dev/vgdata/oracle" in volume group "vgdata" lvchange -- getting status of "/dev/vgdata/oracle" from VGDA in kernel lvchange -- changing logical volume "/dev/vgdata/oracle" in VGDA of kernel lvchange -- ERROR "Operation not permitted" couldn't open logical volume "/dev/vgdata/oracle" Kind Regards, Jules - ----- Good judgement comes from experience, And often experience comes from bad judgement. -----BEGIN PGP SIGNATURE----- Version: PGP Personal Edition 6.0.2 iQA/AwUBOzJh/JIQSDu8ZJkNEQIgTQCeMaw2vpsFCNPoLiuSrZYGAUWJplsAoLll 6joWcPA2bqD9tSAxG1ItYIdU =e50K -----END PGP SIGNATURE-----
