In the beginning I used TOTAL=`ls /d2lmig/*/*/bak/*/* | wc -l` to get a total count. All was good. Until at around 55,000 files I got: -bash: /bin/ls: Argument list too long. Then I used TOTAL=`find /d2lmig/*/*/bak/*/* -name *.bak | wc -l` to get a total count. All was good. Until at around 90,000 files I got: -bash: /usr/bin/find: Argument…

We found it under similar circumstances as others by investigating why a node consumed so much disk space. Failed command-line restores end up in this unmarshall directory. Unmarshalling in Java jargon means: converting…
UPDATE: Have another source who disagrees with Badge who made the claim below. ——— Hopefully this is true. I’d hate to be spreading a false rumor. Anyone willing to confirm? 😀 According to J. L.
