Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.

RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Fixed In Version:	coreutils-8.4-19.el6_4.1	Doc Type:	Bug Fix
Doc Text:	The "tail -f" command uses inotify for tracking changes in files. For remote file systems [-/,] inotify is not available. In the case of unknown file systems, for example panasas, "tail -f" failed instead of falling back to polling. Now, the list of known file systems is updated and "tail -f" is modified to fall back into polling for unknown file systems. As result, "tail -f" now works correctly, even on unknown file systems, with only a warning about the unknown file system and a fall back to polling.Cause: tail -f uses inotify for tracking changes in files. For remote filesystems inotify is not available. Consequence: In the case of unknown filesystems like panasas, tail -f simply failed, instead of fallback to polling. Fix: List of known filesystems was updated and tail was modified to fallback into polling, for unknown filesystems. Result: As result, tail -f will work correctly even on unknown filesystems, just with warning about unknown filesystem and fallback to polling.	Story Points:	---
