Cody,
There were some bugs in earlier versions of 4.x that could cause missing
pool files. But they have been fixed for some time.
How did you determine the cpool directory size (eg, du -sh)?
At any point did you run backups with compression off?
Here's how to find which backup is referencing a particular digest:
- pick an md5 digrest (32 hex characters) that got an error
- take the first 2 hex digits and and it with 0xfe (ie, round down to
the next even number, eg: 0x77 -> 0x76; 0xaf -> 0xae). Call those two
digits XY
- run BackupPC_poolCntPrint TOPDIR/pc/*/*/refCnt/poolCnt.1.XY | less
- use less to search for the hex digest (ie, type "/" then paste the 32
digit digest, then hit return)
- then search upwards to find the file name (ie, type "?Pool Ref", then
hit return
- based on the file name, you can find out the host name and backup
number
To find which directory / file in the specific backup references that
digest, you would need to use BackupPC_ls -R -h HOST -n BackupNUM -s Share
/ | egrep HexDigest
