However, there will be a couple of hundred thousand files missing, mostly in \/store\/mc, because I suspect those files are only available on tape and my tools are very inefficient transferring those files.<\/p>\n\n\n\n

I will switch mostly to CephFS this Thursday. Three directories – \/store\/user, \/store\/temp, and \/store\/unmerged – will stay in HDFS for now. I plan to ask DM team to run consistency check and submit FTS requests that will make CephFS storage consistent with Rucio expectations.<\/p>\n\n\n\n
