[jira] [Commented] (TS-3132) Can't recover the disk, after disk replacement

["Leif Hedstrom (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/TS-3132?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14170996#comment-14170996 ] 

Leif Hedstrom commented on TS-3132:
-----------------------------------

This sounds like maybe a use case for the identifier tags that [~amc] added recently? Assigning this to amc for assessment and comments, I'm thinking this is not an actionable bug, but not sure.
