Hi! I can confirm this. --grow on LVM partition is broken for raid+lvm kickstart installs. bootloader --location=mbr --driveorder=sda,sdb --append="net.ifnames=0 crashkernel=auto rhgb quiet" zerombr clearpart --all --drives=sda,sdb --initlabel part raid.1 --asprimary --size=200 --ondisk=sda part raid.2 --size=1 --grow --ondisk=sda part raid.3 --asprimary --size=200 --ondisk=sdb part raid.4 --size=1 --grow --ondisk=sdb raid /boot --fstype=ext4 --level=RAID1 --device=md0 raid.1 raid.3 raid pv.1 --level=RAID1 --device=md1 raid.2 raid.4 volgroup vg0 --pesize=65536 pv.1 logvol swap --name=swap --vgname=vg0 --size=4096 logvol /tmp --fstype=ext4 --name=tmp --vgname=vg0 --size=4096 --fsoptions="noexec,nosuid,nodev,noatime" logvol / --fstype=ext4 --name=root --vgname=vg0 --size=10240 --grow --fsoptions="defaults,noatime" Such partitioning scheme is now working. Anaconda is complaining about "ValueError: not enough free space in volume group" Buf if I remove --grow from last logvol - everything is ok. I don't understand what I'm doing wrong, such kickstart works flawlessly for C6 installs. 2014-07-16 14:21 GMT+03:00 Borislav Andric <borislav.andric at gmail.com>: > I am testing some kickstarts on ESXi virtual machine with pair of 16GB disks. > Partitioning is lvm over raid. > > If i am using "logvol --grow i get "ValueError: not enough free space in volume group" > Only workaround i can find is to add --maxsize=XXX where XXX is at least 640MB less than available. > (10 extents or 320Mb per created logical volume) > > Following snippet is failing with "DEBUG blivet: failed to set size: 640MB short" > > part raid.01 --size 512 --asprimary --ondrive=sda > part raid.02 --size 1 --asprimary --ondrive=sda --grow > part raid.11 --size 512 --asprimary --ondrive=sdb > part raid.12 --size 1 --asprimary --ondrive=sdb --grow > raid /boot --fstype="xfs" --device="md0" --level=RAID1 raid.01 raid.11 > raid pv.01 --fstype="lvmpv" --device="md1" --level=RAID1 raid.02 raid.12 > volgroup vg0 pv.01 > logvol / --fstype="xfs" --grow --size=4096 --name=lvRoot --vgname=vg0 > logvol swap --fstype="swap" --size=2048 --name=lvSwap --vgname=vg0 > > If i only add --maxsize=13164 everything is working. > (but after install i have 640MB in 20 Free PE in vg0, for details see "after --maxsize install") > > logvol / --fstype="xfs" --grow --size=4096 --name=lvRoot --vgname=vg0 > ------changed to -----> > logvol / --fstype="xfs" --grow --size=4096 --name=lvRoot --vgname=vg0 --maxsize=13164 > > > Some interesting DEBUG lines : > >> 15840MB lvmvg vg0 (26) >> vg0 size is 15840MB >> Adding vg0-lvRoot/4096MB to vg0 >> vg vg0 has 11424MB free > > should it be 11744 or there is 320MB overhead ? > >> Adding vg0-lvSwap/2048MB to vg0 >> vg vg0 has 9056MB free > > 320MB missing again, total of 640MB > >> vg vg0: 9056MB free ; lvs: ['lvRoot', 'lvSwap'] > > nice, i have 9056MB free in vg0 (640MB short but still ... ) > >> 1 requests and 303 (9696MB) left in chunk >> adding 303 (9696MB) to 27 (vg0-lvRoot) > > wtf, who is counting what !! > >> failed to set size: 640MB short > > > Could anyone shed some light ? > > > > > > P.S. > > "after --maxsize install" > ========================= > If i limit root logvol with --maxsize=13164, after installation i get 640MB of free space (20 Free PE). > > > Missing 640Mb is free according to lvm : > [root at c7-pxe-install ~]# pvdisplay > --- Physical volume --- > PV Name /dev/md1 > VG Name vg0 > PV Size 15.49 GiB / not usable 22.88 MiB > Allocatable yes > PE Size 32.00 MiB > Total PE 495 >>>>>>>>>>>Free PE 20<<<<<<<<<<<< > Allocated PE 475 > PV UUID uBLBqQ-Tpao-yPVj-1FVA-488x-Bs0K-ebQOmI > > > And i can use it : > [root at c7-pxe-install ~]# lvextend -L +640M vg0/lvRoot > Extending logical volume lvRoot to 13.47 GiB > Logical volume lvRoot successfully resized > > [root at c7-pxe-install ~]# xfs_growfs / > meta-data=/dev/mapper/vg0-lvRoot isize=256 agcount=4, agsize=841728 blks > = sectsz=512 attr=2, projid32bit=1 > = crc=0 > data = bsize=4096 blocks=3366912, imaxpct=25 > = sunit=0 swidth=0 blks > naming =version 2 bsize=4096 ascii-ci=0 ftype=0 > log =internal bsize=4096 blocks=2560, version=2 > = sectsz=512 sunit=0 blks, lazy-count=1 > realtime =none extsz=4096 blocks=0, rtextents=0 > data blocks changed from 3366912 to 3530752 > [root at c7-pxe-install ~]# pvdisplay > --- Physical volume --- > PV Name /dev/md1 > VG Name vg0 > PV Size 15.49 GiB / not usable 22.88 MiB > Allocatable yes (but full) > PE Size 32.00 MiB > Total PE 495 > Free PE 0 > Allocated PE 495 > PV UUID uBLBqQ-Tpao-yPVj-1FVA-488x-Bs0K-ebQOmI > > [root at c7-pxe-install ~]# > _______________________________________________ > CentOS mailing list > CentOS at centos.org > http://lists.centos.org/mailman/listinfo/centos
