Hello TCLUG, I have a CentOS vm with a 405 GB disk. My issue is that there is about 90 GB missing from an LV. fdisk reports the size of /dev/sdb1 at 434 GB, pvdisplay reports 405 GB, lvdisplay reports 405 GB, but df -h report 312 GB. Can anyone point me in the right direction? I'll put the output of various things below. Thanks, Rob -- [root at db06 Fri Nov 07 @ 10:54:50 ~]$ df -h Filesystem Size Used Avail Use% Mounted on /dev/mapper/VolGroup00-LogVol00 5.8G 1.8G 3.8G 32% / /dev/sda1 99M 19M 76M 20% /boot tmpfs 7.8G 0 7.8G 0% /dev/shm /dev/mapper/DBDATA-data 312G 232G 65G 79% /LVM/data /dev/mapper/DBDATA-extra 119G 188M 112G 1% /LVM/extra -- [root at db06 Fri Nov 07 @ 10:55:13 ~]$ fdisk -l Disk /dev/sda: 8589 MB, 8589934592 bytes 255 heads, 63 sectors/track, 1044 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/sda1 * 1 13 104391 83 Linux /dev/sda2 14 1044 8281507+ 8e Linux LVM Disk /dev/sdb: 434.8 GB, 434865438720 bytes 255 heads, 63 sectors/track, 52869 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/sdb1 1 52869 424670211 8e Linux LVM Disk /dev/sdc: 128.8 GB, 128849018880 bytes 255 heads, 63 sectors/track, 15665 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/sdc1 1 15665 125829081 8e Linux LVM -- [root at db06 Fri Nov 07 @ 10:55:47 ~]$ pvdisplay --- Physical volume --- PV Name /dev/sdb1 VG Name DBDATA PV Size 405.00 GB / not usable 835.00 KB Allocatable yes (but full) PE Size (KByte) 4096 Total PE 103679 Free PE 0 Allocated PE 103679 PV UUID 95qPah-UTJf-febW-4ZhR-vCev-ILXo-zzdCJI --- Physical volume --- PV Name /dev/sdc1 VG Name DBDATA PV Size 120.00 GB / not usable 3.96 MB Allocatable yes (but full) PE Size (KByte) 4096 Total PE 30719 Free PE 0 Allocated PE 30719 PV UUID gU3dvV-cYTC-Wkvh-OUhG-oOuP-cWmC-njN0BJ --- Physical volume --- PV Name /dev/sda2 VG Name VolGroup00 PV Size 7.90 GB / not usable 23.41 MB Allocatable yes (but full) PE Size (KByte) 32768 Total PE 252 Free PE 0 Allocated PE 252 PV UUID Wrcluh-it01-DpPH-8ppE-gy7u-s8Qd-tOYLcs [root at db06 Fri Nov 07 @ 10:56:19 ~]$ -- [root at db06 Fri Nov 07 @ 10:57:18 ~]$ vgdisplay --- Volume group --- VG Name DBDATA System ID Format lvm2 Metadata Areas 2 Metadata Sequence No 11 VG Access read/write VG Status resizable MAX LV 0 Cur LV 2 Open LV 2 Max PV 0 Cur PV 2 Act PV 2 VG Size 524.99 GB PE Size 4.00 MB Total PE 134398 Alloc PE / Size 134398 / 524.99 GB Free PE / Size 0 / 0 VG UUID Czj6wk-NLG6-XVRc-f0Ll-r06d-nGFb-l4qq17 --- Volume group --- VG Name VolGroup00 System ID Format lvm2 Metadata Areas 1 Metadata Sequence No 3 VG Access read/write VG Status resizable MAX LV 0 Cur LV 2 Open LV 2 Max PV 0 Cur PV 1 Act PV 1 VG Size 7.88 GB PE Size 32.00 MB Total PE 252 Alloc PE / Size 252 / 7.88 GB Free PE / Size 0 / 0 VG UUID Boxzpe-Twkz-1Fci-lnfl-dzMI-d93u-RPm2Yr -- [root at db06 Fri Nov 07 @ 10:57:29 ~]$ lvdisplay --- Logical volume --- LV Name /dev/DBDATA/data VG Name DBDATA LV UUID 2Fb3ar-CSYP-o1kF-yvws-H6Tv-677L-Ok8IM7 LV Write Access read/write LV Status available # open 1 LV Size 405.00 GB Current LE 103679 Segments 1 Allocation inherit Read ahead sectors auto - currently set to 256 Block device 253:2 --- Logical volume --- LV Name /dev/DBDATA/extra VG Name DBDATA LV UUID ygs7qh-bK3T-4fac-aFbl-SxDM-z9wb-JAIwfm LV Write Access read/write LV Status available # open 1 LV Size 120.00 GB Current LE 30719 Segments 1 Allocation inherit Read ahead sectors auto - currently set to 256 Block device 253:3 --- Logical volume --- LV Name /dev/VolGroup00/LogVol00 VG Name VolGroup00 LV UUID eQbwV2-2qsK-U2au-e309-wUe1-SfPy-Z5mBpm LV Write Access read/write LV Status available # open 1 LV Size 5.94 GB Current LE 190 Segments 1 Allocation inherit Read ahead sectors auto - currently set to 256 Block device 253:0 --- Logical volume --- LV Name /dev/VolGroup00/LogVol01 VG Name VolGroup00 LV UUID g7tx8y-D3ef-CpCk-MQSa-b1jM-7kXK-IHTX55 LV Write Access read/write LV Status available # open 1 LV Size 1.94 GB Current LE 62 Segments 1 Allocation inherit Read ahead sectors auto - currently set to 256 Block device 253:1
