Increase lvol size in HP-UX
Posted by Lincoln Zuljewic Silva in HP-UX on May 7, 2010
Let’s assume that you want to increase 1Gb of the /dev/MyVG /lvol1 device (mounted as /filesystem):
# bdf /filesystem
Filesystem kbytes used avail %used Mounted on
/dev/ MyVG /lvol1
573440000 533892407 37080557 94% /filesystem
The actual size is 573440000 Kb (573 Gb) and you will increase it to 574440000 Kb (574 Gb).
- Check if there is available space in the Volume Group:
# vgdisplay MyVG
--- Volume groups ---
VG Name /dev/MyVG
VG Write Access read/write
VG Status available
Max LV 255
Cur LV 1
Open LV 1
Max PV 100
Cur PV 17
Act PV 17
Max PE per PV 15000
VGDA 34
PE Size (Mbytes) 16
Total PE 36907
Alloc PE 35000
Free PE 1907
Total PVG 1
Total Spare PVs 0
Total Spare PVs in use 0
Note the “Free PE” and “PE Size (Mbytes)”. It say that you has 30512 Mb (30Gb) available in MyVG (Free PE * PE Size).
- Increase the lvol:
# lvextend -L 574440 /dev/MyVG/lvol1 * the syntax is: lvexten -L <new size in Mb> <lvol path>
- Now, increase the filesystem:
# fsadm -b 574440m /filesystem * the syntax is: fsadm –b <new size in Mb> <mount point>
Disable file size limit in AIX
Posted by Lincoln Zuljewic Silva in Aix on December 4, 2009
By default, if you try do copy/create a file larger than 2Gb in AIX, you will get a “file too large” message. That happen because AIX have a default limit of 2Gb for files.
To disable (or increase) this limit, edit /etc/security/limits and change the parameter fsize to “-1” or whatever value you want.
You can change it in “default” to apply to all users or change it to a specific user.
Remember that the file system should be JFS2.
