lvm crashes my machine
I have created a logical volume striped over 8 17G disks, with a stripe size of 64K. The the device is mounted, and everything looks fine (i.e. "df -k" shows ca. 136 GB, for the logical volume size). I can write small data on the device, but when I try to ftp a 5G file on this volume, the system crashes, and I have to reboot. what have I done wrong ?!?
help will be appreciated.

Re: lvm crashes my machine
1. Can you post tail -10 of your /var/adm/syslog/OLDsyslog.log?.
2. Is this server in a service guard cluster or on a disk array that being shared by other servers? If so, are you sure you did not use any of the disks that are being used by other server?
3. What is the patch level on this system?.
4. How do the command "vgdisplay -v" respond?. Are you seeing any errors?.
5. Are you seeing any errors while the system is booting?.

Re: lvm crashes my machine
What OS & JFS versions are you running?
Are your patches up to date?
Do you have largefiles enabled on this FS?
Rgds,
Jeff

Re: lvm crashes my machine
I am using redhat linux 7.1 with kernel version 2.4.18, but hoped to get the answer from this forum.
lvm = verison 1.1. Haven't applied any patch yet.
vgdisplay -v shows no errors,

The man page for mkfs doesn't say how to enable largefile support during filesystem creation.
/etc/rc.log doesn't exist on my machine.
gotta try and enable largefile support though
thanks

Re: lvm crashes my machine
Well, I'm not much of a penguin-head. Have my hands full with HP-UX.
In HP-UX, during FS creation you'd use the -o largefiles parameter. And if afterward you want to turn on largefiles you'd run
fsadm -o largefiles /dev/vg_name/lv_name
You can just run
fsadm /dev/vg_name/lv_name
to see what's turned on & off on the FS.
Rgds,
Jeff

Re: lvm crashes my machine
Everything should work exactly the same. When creating filesystmems, you probably need to change the -F fstype part of the command line to include a valid Linux fs type.
LVM is great on HP-UX and may become the defact standard on Linux.
