A method for updating file system entity (FSE) metadata. The method may include receiving, by a first computing entity, a request to perform a case-sensitive FSE operation that comprises one of (a) adding a case-sensitive version of a name of a FSE to a data structure, or (b) deleting the case-sensitive version of the name of the FSE from the data structure, the data structure comprises multiple name blocks; finding, by the first computing entity, a certain name block of the multiple name blocks that is associated with the case-sensitive version of the name of the FSE. The method may also include determining, by the first computing entity, whether (a) the certain name block is associated with a case-insensitive version of the name of the FSE, and whether (b) the first computing entity preceded a second computing entity in reaching the certain name block, the second computing entity was requested to perform a case-insensitive FSE operation that corresponds to the case-sensitive FSE operation; when it is found that (a) the certain name block is associated with the case-insensitive version of the name of the FSE, and (b) the first computing entity preceded the second computing entity in reaching the certain name block, then: a) informing the second computing entity that the first computing entity takes over a performing of the corresponding case-insensitive FSE operation; and b) performing the corresponding case-insensitive FSE operation by the first computing entity.
