fsck bootflash: target is busy, ISR 4331

[resourcesglobal]

Hi all,

Wonder if anyone has come across this.  I noticed sda1 drive errors in my log and am trying to run FSCK but I get the following errors.  Anyone know how I can find what is keeping bootflash busy?  This has worked on identical 4331's in our environment.  Thanks in advanced!

NYC-4331#fsck bootflash:
umount: /bootflash: target is busy
        (In some cases useful info about processes that
         use the device is found by lsof(8) or fuser(1).)

%Error: could not unmount bootflash
/bin/ln: failed to create symbolic link './sda1': File exists
mount: /dev/sda1 is already mounted or /bootflash busy
       /dev/sda1 is already mounted on /bootflash
fsck error: can not unmount /bootflash, device is busy
%Error checking bootflash: (I/O error)

Hello, have you had any luck resolving this?

Started seeing this issue on some ISRs after upgrading to 16.9.4 Wondering if anyone has found a solution/workaround. Seems like there are about 5 google results for this error so does not seem a common issue.
