Title: disk space error...something very peculiar! Post by: Michael on November 17, 2006, 07:27:17 PM Quote Topic: disk space error...something very peculiar!

This system has no free space at /home filesystem at this time. We have only 900M data on /home. systems rootvg shows that the PP size is 64M and /home mounted on rootvg has 200 PPs. Therefore 200 * 64 = 12800 means we should have a filesystem which has 12.8GByte. But df -m shows we have a /home filesystem which has only 3GByte with no free space. # lspv|grep rootvg hdisk0 000cec8e2ce9663e rootvg active yes we have total 3 HDs installed in this system. # lspv hdisk0 000cec8e2ce9663e rootvg active hdisk1 000cec8ec654d5ba datavg active hdisk2 005b68ec33ac7a01 datavg active We are using this server as database (oracle) and application server. # lsvg rootvg VOLUME GROUP: rootvg VG IDENTIFIER: 000cec8e00004c00000001042ce983d7 VG STATE: active PP SIZE: 64 megabyte(s) VG PERMISSION: read/write TOTAL PPs: 542 (34688 megabytes) MAX LVs: 256 FREE PPs: 5 (320 megabytes) LVs: 17 USED PPs: 537 (34368 megabytes) OPEN LVs: 13 QUORUM: 2 TOTAL PVs: 1 VG DESCRIPTORS: 2 STALE PVs: 0 STALE PPs: 0 ACTIVE PVs: 1 AUTO ON: yes MAX PPs per PV: 1016 MAX PVs: 32 LTG size: 128 kilobyte(s) AUTO SYNC: no HOT SPARE: no BB POLICY: relocatable # lsvg rootvg -l rootvg: LV NAME TYPE LPs PPs PVs LV STATE MOUNT POINT hd5 boot 1 1 1 closed/syncd N/A hd6 paging 64 64 1 open/syncd N/A hd8 jfslog 1 1 1 open/syncd N/A hd4 jfs 2 2 1 open/syncd / hd2 jfs 24 24 1 open/syncd /usr hd9var jfs 2 2 1 open/syncd /var hd3 jfs 9 9 1 open/syncd /tmp hd1 jfs 200 200 1 open/syncd /home hd10opt jfs 1 1 1 open/syncd /opt lv00 jfs 47 47 1 closed/syncd /ptf loglv00 jfs2log 1 1 1 open/syncd N/A fslv00 jfs2 48 48 1 open/syncd /bea lvora jfs2 81 81 1 open/syncd /oracle ptcl2_redo01 raw 8 8 1 closed/syncd N/A ptcl2_redo02 raw 8 8 1 open/syncd N/A ptcl2_redo03 raw 8 8 1 closed/syncd N/A lvbill jfs2 32 32 1 open/syncd /bill # df -m Filesystem MB blocks Free %Used Iused %Iused Mounted on /dev/hd4 128.00 92.93 28% 2018 4% / /dev/hd2 1536.00 24.34 99% 31878 9% /usr /dev/hd9var 128.00 12.62 91% 610 2% /var /dev/hd3 576.00 481.65 17% 279 1% /tmp /dev/hd1 3072.00 20.90 100% 15126 2% /home /proc - - - - - /proc /dev/hd10opt 64.00 28.31 56% 626 4% /opt /dev/fslv00 3072.00 1208.51 61% 19071 7% /bea /dev/lvora 5184.00 412.23 93% 16058 15% /oracle /dev/lvoradata 37120.00 1488.08 96% 26 1% /oradata /dev/lvbill 2048.00 1099.20 47% 3637 2% /bill /dev/lvjfdata 29312.00 8252.37 72% 27601 2% /jfdata # du -sm /home 878.23 /home please if anybody can indentify the problem/solution.

Post by: Michael on November 17, 2006, 07:42:24 PM OK. I will have to guess here, but I expect that rather than using chfs -a size+XXX /home to increase filesystem size, the command extendlv has been used instead.
i.e. extendlv XX hd1 The output of lsfs states that the filesystem size is blocks is: 6291456 blocks A filesystem of 1PP of 64MB has 131072 512 byte blocks, so the following command shows that the filesyetem is only using 48 of the 200 PP. Quote michael@x054:[/home/michael]dc 6291456 131072 / p 48 What I would recommend is that you use the following commands to use all the space you have allocated: chlv -x 200 hd1 chfs -a size=13.2G /home I am not certain that the size is correct. Another way that should be exact is: Quote michael@x054:[/home/michael]dc 131072 200 * p 26214400 chfs -a size=2621440 /home Hope this works as expected. |
