[PATCH] nfsdcld: prevent from accessing /var/lib/nfs/nfsdcld in read-only file system during boot

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



I saw a VMWare guest that hit a rare condition during boot;
nfsdcld started too early to check access on /var/lib/nfs/nfsdcld which were
still in read-only file system as follows:

  nfsdcld[...]: Unexpected error when checking access on /var/lib/nfs/nfsdcld: Read-only file system
  systemd[1]: nfsdcld.service: Main process exited, code=exited, status=226/NAMESPACE
  systemd[1]: nfsdcld.service: Failed with result 'exit-code'.

nfsdcld.service needs to wait the root file system to be remounted at least.
