I was trying to copy a whole directory tree to a new disk using:
``cp -p -r marko /mnt/usr/''
There's about 29,000 files (~560MB). After about 80% has been copied
cp just hangs. ps(1) shows it as idle. I tried again, same thing.
I identified the sub-dirs that hadn't been copied and copied them
(cp -p -r) one at a time. This worked for all but one directory.
I tried several times, but this one dir (which contains sub-dirs)
just hangs cp.
I dropped to single-user, umnounted the filesystems and fsck'd both
the source and target filesystems, no errors reported.
I can tar this dir into a file and un-tar it in the new location
and all the files are there and ``ls -R'' lists all the files in
the source directory and below. It just seems to be cp that has
a problem.
I made a debug version of cp and ran it from gdb. When it hung I
stopped it with Ctrl-Z and did a stack trace. This is the output:
^Z
Program received signal SIGTSTP, Stopped (user).
0x804a94c in _open ()
(gdb) bt
#0 0x804a94c in _open ()
#1 0x8048cb1 in copy_file (entp=0x8070600, dne=1) at utils.c:70
#2 0x8048bb9 in copy (argv=0xefbfdaa8, type=FILE_TO_DIR, fts_options=6)
at cp.c:407
#3 0x8048665 in main (argc=1, argv=0xefbfdaa8) at cp.c:240
#4 0x80480e9 in _start ()
(gdb)
Unfortunately this is about the limit of my gdb skills.
Can anyone make any sense of this, and tell me why this dir won't
copy?
Is it a bug in cp or is there possibly a filesystem problem, despite
fsck reporting everything is OK?
