Hello!
I'm trying to move a filesystem to a new larger RAID volume. The old
filesystem was using gjournal, and I have also created the new
filesystem with gjournal. The FS in question holds the DocumentRoot of
our web server, and in its depths, a couple of fairly large (several
gigabytes) files are lurking.
I've mounted the new FS under /mnt and use tar to transfer the files:
cd /mnt
tar -c -v -f - -C /docroot . | tar xf -
It seems that these large files cause a problem. Sometimes when the
process reaches one of these files, the machine reboots. It doesn't
create a crashdump in /var/crash, which may be because the system has
less swap (2 GB) than RAM (8 GB). Fortunately the machine comes back
up OK, except that the target FS (/mnt) is corrupt and needs to be
fsck'd. I've tried to re-run the process three times now, and caused
the machine to crash as it reaches one or another large file. Any
ideas what I should do to avoid the crash?
The OS version is 7.3 (amd64).
