LINUX - HOW TO KILL PROCESSES USING LOGICAL VOLUME

 

 

1. Run below command to identify if any there are any processes using Logical volume.
   
   dmsetup info -c | grep -i vol
   
   Foe e.g. below is snippet
   
   VolGroup00-LogVol01 249   3 L--w    0    1      0 LVM-rpBRPhVlR53KlK84BjyAJyQLshSAuvwslMtyXi7CFOwEwk2s7x8HMF1XYiSuA1xk
   
   VolGroup00-LogVol00 249   2 L--w    1    1      0 LVM-rpBRPhVlR53KlK84BjyAJyQLshSAuvws3BdEwehKDtBsn3Mxbq3M3ViGfSKQ3LXe
   
   
   Take note of the 5th column, which indicates if a volume is “open,” and the 2nd and 3rd columns, which are the major and minor IDs, respectively.
2. Find any process attached to this volume by searching on the major and minor IDs discovered above:
   
   # lsof | grep "major,minor"
   
   For e.g. below command.
   
   lsof | grep "249,2"
   
   Below is snippet
   
   bash      28030    root  txt       REG              249,2    964608   17870842 /usr/bin/bash
   bash      28030    root  mem       REG              249,2             25446063 /usr/lib64/libnss_files-2.17.so (stat: No such file or directory)\
   bash      28030    root  mem       REG              249,2             17013053 /usr/lib/locale/locale-archive (path dev=8,2, inode=517470)
   bash      28030    root  mem       REG              249,2             25168083 /usr/lib64/libc-2.17.so (stat: No such file or directory)
   
   
3. Kill the processes using the logical volume in above step 2 using kill -9 command.
