ROOT 6.15/01Built for linuxx8664gcc heads/master@v6-13-04-536-g67ea09a
I am trying to merge files .root with the command line
hadd data.root file1.root file2.root ...file20.root
OBS: All files = 180Gb.
and I get the error message that say:
Fatal in <TFileMerger::RecursiveRemove>: Output file of the TFile Merger (targeting data.root) has been deleted (likely due to a TTree larger than 100Gb)
What I am trying to do to solve this is to set new size
TTree::SetMaxTreeSize but is not working, I did:
root  TTree::SetMaxTreeSize(1000000000000LL); // 1TB root  TTree::GetMaxTreeSize() (long long) 1000000000000
Someone can help me to solve this.
Thank you very much,
