I can't work out whats going on with my nightly cpio backup.
If I do:
cd /
find . -print | cpio -ocv 2>$OUT > /dev/st0
and read back the contents using
cpio -itv </dev/st0
we get a partial list of files and then:
cpio: memory exhausted
I have tried using dd to get some data from the tape and then
cpio -itv <dd.out
I still get the cpio error after less than 1 minute. I read back ~ 300Mb so
it has not reached the end of the archive file.
I am using Mandrake 7.1 kernel 2.2.15-4mdk with an adaptec scsi card and
20Gb DAT drive.
It does not look like a memory problem as I still have free memory and can
vi a 13Mb file.
I have been trying to narrow down this problem by using cpio to backup
a small number of files, both to disk and tape but not got this error yet.
However I have came accross another strange problem with cpio in that
I can't get a list of files backup from std err. e.g.
find . -depth -print | cpio -ocv 2>../backup.log >../backup.cpio
cat ../backup.log
1129 blocks
but i should get a list of files in backup.log, as I do with the same cmd
running on a Red Hat 6.0 2.2.5-22 server with same tape device.
I can read the tape onto a sco box using gnu cpio by:
dd if=/dev/rmt/ctape2 bs=32k | cpio -icvdumB
Any ideas? I had thought that there could have been a hardware error with
the scsi card
