I did the following to create a snapshot of an active filesystem to try
to make a consistent copy of it:
# lvcreate --extents 30 --snapshot --name home2snap /dev/sys/home2gb
...
lvcreate -- INFO: using default snapshot chunk size of 64 KB for "/dev/sys/home\
2snap"
lvcreate -- doing automatic backup of "sys"
lvcreate -- logical volume "/dev/sys/home2snap" successfully created
# lvdisplay /dev/sys/home2gb
--- Logical volume ---
LV Name /dev/sys/home2gb
VG Name sys
LV Write Access read/write
LV snapshot status source of
/dev/sys/home2snap [active]
Segmentation fault
# lvdisplay /dev/sys/home2gb
--- Logical volume ---
LV Name /dev/sys/home2gb
VG Name sys
LV Write Access read/write
LV snapshot status source of
/dev/sys/home2snap [active]
Segmentation fault

<At this point I lost my remote connection to the machine and presume it
crashed; it probably didn't reboot, since subsequent attempts to
reconnect via ssh failed and ping failed as well.>
The kernel is probably 1.0.3 (Debian SPARC sun4u 2.4.21 up) and the lvm
tools are 1.0.8.
Any suggestions for avoiding these seg faults and the system crash?
Sincerely,
