Hi,
Debian unstable here with mariadb 11.8.2-1
When I am trying to uncompress a maybe compressed table with parallel-recovers it stalls in around 268KB of TMD file. The original table is 2GB compressed and 3.4GB uncompressed.
For now I remove the --parallel-recover flag.
Any ideas?
root@node00:# ps auxw | grep myisamchk
